inputs.conf
The following are the spec and example files for inputs.conf.
inputs.conf.spec
# Version 9.0.8 #
OVERVIEW
# This file contains possible settings you can use to configure inputs, # distributed inputs such as forwarders, and file system monitoring in # inputs.conf. # # Each stanza controls different search commands settings. # # There is an inputs.conf file in the $SPLUNK_HOME/etc/system/default/ directory. # Never change or copy the configuration files in the default directory. # The files in the default directory must remain intact and in their original # location. # # To set custom configurations, create a new file with the name inputs.conf in # the $SPLUNK_HOME/etc/system/local/ directory. Then add the specific settings # that you want to customize to the local configuration file. # For examples, see inputs.conf.example. # # You must restart the Splunk platform instance to enable configuration changes. # # To learn more about configuration files (including file precedence) see the # documentation located at # http://docs.splunk.com/Documentation/Splunk/latest/Admin/Aboutconfigurationfiles #
GLOBAL SETTINGS
# Use the [default] stanza to define any global settings.
# * You can also define global settings outside of any stanza, at the top of
# the file.
# * Each .conf file should have at most one default stanza. If there are
# multiple default stanzas, settings are combined. In the case of
# multiple definitions of the same setting, the last definition in the
# file wins.
# * If an setting is defined at both the global level and in a specific
# stanza, the value in the specific stanza takes precedence.
############################################################################
# GENERAL SETTINGS:
# The following settings are valid for all input types (except file system
# change monitor, which is described in a separate section in this file).
# You must first enter a stanza header in square brackets, specifying the input
# type. See later in this file for examples. Then, use any of the
# following settings.
#
# To specify global settings for Windows Event Log inputs, place them in
# the [WinEventLog] global stanza as well as the [default] stanza.
############################################################################
host = <string>
* Sets the host key/field to a static value for this input stanza.
* The input uses this field during parsing and indexing. It also uses this
field at search time.
* As a convenience, the input prepends the chosen string with 'host::'.
* When set to '$decideOnStartup', sets the field to the hostname of executing
machine. The hostname is checked and the field set at every splunkd startup.
* If you run multiple instances of the software on the same machine (hardware
or virtual machine), choose unique values for 'host' to differentiate
your data, ex. myhost-sh-1 or myhost-idx-2.
* Do not put the <string> value in quotes. Use host=foo, not host="foo".
* When 'host' is set to "$decideOnStartup", you can further control how splunkd
derives the hostname by using the 'hostnameOption' setting in server.conf.
* For example, if you want splunkd to use the fully qualified domain
name for the machine, set "host = $decideOnStartup" in inputs.conf and
"hostnameOption = fullyqualifiedname" in server.conf.
* More information on hostname options can be found in the server.conf
specification file.
* If you remove the 'host' setting from $SPLUNK_HOME/etc/system/local/inputs.conf
or remove $SPLUNK_HOME/etc/system/local/inputs.conf, the setting reverts to
"$decideOnStartup". Apps that need a resolved host value should use the
'host_resolved' property in the response for the REST 'GET' call of the
input source. This property is set to the hostname of the local Splunk
instance. It is a read only property that is not written to inputs.conf.
* Default: "$decideOnStartup"
run_only_one= <boolean>
* Determines if a scripted or modular inputs runs on one search head
in SHC.
* Currently not supported. This setting is related to a feature that is
still under development.
* Default: true
index = <string>
* Sets the index to store events from this input.
* Primarily used to specify the index to store events that come in through
this input stanza.
* Default: main (or whatever you have set as your default index)
source = <string>
* Sets the source key/field for events from this input.
* Detail: Sets the source key initial value. The key is used during
parsing/indexing, in particular to set the source field during
indexing. It is also the source field used at search time.
* As a convenience, the chosen string is prepended with 'source::'.
* Avoid overriding the source key. The input layer provides a more accurate
string to aid in problem analysis and investigation, recording the file
from which the data was retrieved. Consider using source types, tagging,
and search wildcards before overriding this value.
* Do not put the <string> value in quotes: Use source=foo,
not source="foo".
* Default: the input file path
sourcetype = <string>
* Sets the sourcetype key/field for events from this input.
* Explicitly declares the source type for this input instead of letting
it be determined through automated methods. This is important for
search and for applying the relevant configuration for this data type
during parsing and indexing.
* Sets the sourcetype key initial value. The key is used during
parsing or indexing to set the source type field during
indexing. It is also the source type field used at search time.
* As a convenience, the chosen string is prepended with 'sourcetype::'.
* Do not put the <string> value in quotes: Use sourcetype=foo,
not sourcetype="foo".
* If not set, the indexer analyzes the data and chooses a source type.
* No default.
queue = [parsingQueue|indexQueue]
* Sets the queue where the input processor deposits the events it reads.
* Set to "parsingQueue" to apply the props.conf file and other parsing rules to
your data. For more information about the props.conf file and rules
timestamps and linebreaks, see the props.conf file and the
online documentation at http://docs.splunk.com/Documentation.
* Set to "indexQueue" to send your data directly into the index.
* Default: parsingQueue
# Pipeline Key defaulting.
* Pipeline keys in general can be defaulted in inputs stanzas.
* The list of user-available, modifiable pipeline keys is described in
transforms.conf.spec. See transforms.conf.spec for further information on
these keys.
* The currently-defined keys which are available literally in inputs stanzas
are as follows:
queue = <value>
_raw = <value>
_meta = <value>
_time = <value>
* Inputs have special support for mapping host, source, sourcetype, and index
to their metadata names such as host -> Metadata:Host
* Defaulting these values is not recommended, and is
generally only useful as a workaround to other product issues.
* Defaulting these keys in most cases overrides the default behavior of
input processors, but this behavior is not guaranteed in all cases.
* Values defaulted here, as with all values provided by inputs, can be
altered by transforms at parse time.
############################################################################
# This section contains options for routing data using inputs.conf rather than
# outputs.conf.
#
# NOTE: Concerning routing via inputs.conf:
# This is a simplified set of routing options you can use as data comes in.
# For more flexible options or details on configuring required or optional
# settings, see outputs.conf.spec.
############################################################################
_TCP_ROUTING = <comma-separated list>
* A comma-separated list of tcpout group names.
* This setting lets you selectively forward data to one or more specific indexers.
* Specify the tcpout group that the forwarder uses when forwarding the data.
The tcpout group names are defined in outputs.conf with
[tcpout:<tcpout_group_name>].
* To forward data to all tcpout group names that have been defined in
outputs.conf, set to '*' (asterisk).
* To forward data from the "_internal" index, you must explicitly set
'_TCP_ROUTING' to either "*" or a specific splunktcp target group.
* Default: The groups specified in 'defaultGroup' in [tcpout] stanza in
the outputs.conf file
_SYSLOG_ROUTING = <comma-separated list>
* A comma-separated list of syslog group names.
* Use this setting to selectively forward the data to specific destinations as
syslog events.
* Specify the syslog group to use when forwarding the data.
The syslog group names are defined in outputs.conf with
[syslog:<syslog_group_name>].
* The destination host must be configured in outputs.conf, using
"server=[<ip>|<servername>]:<port>".
* This setting does not work on a universal forwarder.
* Default: The groups specified in 'defaultGroup' in the [syslog] stanza in
the outputs.conf file
_INDEX_AND_FORWARD_ROUTING = <string>
* If set for any input stanza, causes all data coming from that input
stanza to be labeled with this setting.
* When 'selectiveIndexing' is in use on a forwarder:
* Data without this label will not be indexed by that forwarder.
* Data with this label will be indexed in addition to any forwarding.
* This setting does not actually cause data to be forwarded or not forwarded in
any way, nor does it control where the data is forwarded in multiple-forward
path cases.
* Only has effect if you use the 'selectiveIndexing' feature in outputs.conf.
* Default: not set
Deny list
[blacklist:<path>] * Protects files on the file system from being indexed or previewed. * The input treats a file as denied if the file starts with any of the defined deny list <paths>. * Adding a file to the deny list with the specified path occurs even if a monitor stanza defines an allow list that matches the file path. * The preview endpoint returns an error when asked to preview an excluded file. * The oneshot endpoint and command also returns an error. * When a denied file is monitored, using monitor:// or batch://, the 'filestatus' endpoint shows an error. * For fschange with the 'sendFullEvent' option enabled, contents of denied files are not indexed.
Input types
Valid input stanzas, along with their input-specific settings:
MONITOR:
[monitor://<path>]
* Configures a file monitor input to watch all files in the <path> you specify.
* <path> can be an entire directory or a single file.
* You must specify the input type and then the path, so put three slashes in
your path if you are starting at the root on *nix systems (to include the
slash that indicates an absolute path).
# Additional settings:
host_regex = <regular expression>
* If specified, <regular expression> extracts host from the path to the file
for each input file.
* Detail: This feature examines the source key; if source is set
explicitly in the stanza, that string is matched, not the original
filename.
* Specifically, the first group of the regular expression (regex) is used
as the host.
* If the regex fails to match, the input uses the default 'host' setting.
* If 'host_regex' and 'host_segment' are both set, the input ignores 'host_regex'.
* No default.
host_segment = <integer>
* If set to N, the Splunk platform sets the Nth "/"-separated segment of the path
as 'host'.
* For example, if you set "host_segment = 3" and the path is
/logs/servers/host08/abc.txt, the third segment, "host08", is used.
* If the value is not an integer or is less than 1, the default 'host'
setting is used.
* On Windows machines, the drive letter and colon before the backslash *does not*
count as one segment.
* For example, if you set "host_segment = 3" and the monitor path is
D:\logs\servers\host01, Splunk software sets the host as "host01" because
that is the third segment.
* No default.
whitelist = <regular expression>
* If set, files from this input are monitored only if their path matches the
specified regular expression.
* Takes precedence over the deprecated '_whitelist' setting, which functions
the same way.
* No default.
blacklist = <regular expression>
* If set, files from this input are NOT monitored if their path matches the
specified regex.
* Takes precedence over the deprecated '_blacklist' setting, which functions
the same way.
* If a file matches the regexes in both the deny list and allow list settings,
the file is NOT monitored. Deny lists take precedence over allow lists.
* No default.
NOTE concerning wildcards and monitor:
* You can use wildcards to specify your input path for monitored inputs. Use
"..." for recursive directory matching and "*" for wildcard matching in a
single directory segment.
* "..." searches recursively through one or more directories. This means that
/foo/.../bar matches foo/1/bar, foo/1/2/bar, etc.
* You can use multiple "..." specifications in a single input path. For
example: /foo/.../bar/...
* The asterisk (*) matches anything in a single path segment; unlike "...", it
does not search recursively. For example, /foo/*/bar matches the files
/foo/1/bar, /foo/2/bar, etc. However, it does not match
/foo/bar or /foo/1/2/bar.
A second example: /foo/m*r/bar matches /foo/mr/bar, /foo/mir/bar,
/foo/moor/bar, etc. It does not match /foo/mi/or/bar.
* You can combine "*" and "..." as needed: foo/.../bar/* matches any file in
the bar directory within the specified path.
* A monitor stanza path will interpret regular expression metacharacters as
strings unless they are preceded by the wildcard values "*" or "..." in a prior
segment of the path.
* In the case where multiple unique monitor inputs overlap through the use of
wildcards or specific paths defined in the monitor stanza, the Splunk platform
processes the files using the monitor stanza that is the closest
specific match.
crcSalt = <string>
* Use this setting to force the input to consume files that have matching CRCs,
or cyclic redundancy checks.
* By default, the input only performs CRC checks against the first 256
bytes of a file. This behavior prevents the input from indexing the same
file twice, even though you might have renamed it, as with rolling log
files, for example. Because the CRC is based on only the first
few lines of the file, it is possible for legitimately different files
to have matching CRCs, particularly if they have identical headers.
* If set, <string> is added to the CRC.
* If set to the literal string "<SOURCE>" (including the angle brackets), the
full directory path to the source file is added to the CRC. This ensures
that each file being monitored has a unique CRC. When 'crcSalt' is invoked,
it is usually set to <SOURCE>.
* Be cautious about using this setting with rolling log files; it could lead
to the log file being re-indexed after it has rolled.
* In many situations, 'initCrcLength' can be used to achieve the same goals.
* Default: empty string
initCrcLength = <integer>
* How much of a file, in bytes, that the input reads before trying to
identify whether it has already seen the file.
* You might want to adjust this if you have many files with common
headers (comment headers, long CSV headers, etc) and recurring filenames.
* Cannot be less than 256 or more than 1048576.
* CAUTION: Improper use of this setting causes data to be re-indexed. You
might want to consult with Splunk Support before adjusting this value - the
default is fine for most installations.
* Default: 256 (bytes)
ignoreOlderThan = <non-negative integer>[s|m|h|d]
* The monitor input compares the modification time on files it encounters
with the current time. If the time elapsed since the modification time
is greater than the value in this setting, Splunk software puts the file
on the ignore list.
* Files on the ignore list are not checked again until the Splunk
platform restarts, or the file monitoring subsystem is reconfigured. This
is true even if the file becomes newer again at a later time.
* Reconfigurations occur when changes are made to monitor or batch
inputs through Splunk Web or the command line.
* Use 'ignoreOlderThan' to increase file monitoring performance when
monitoring a directory hierarchy that contains many older, unchanging
files, and when removing or adding a file to the deny list from the
monitoring location is not a reasonable option.
* Do NOT select a time that files you want to read could reach in
age, even temporarily. Take potential downtime into consideration!
* Suggested value: 14d, which means 2 weeks
* For example, a time window in significant numbers of days or small
numbers of weeks are probably reasonable choices.
* If you need a time window in small numbers of days or hours,
there are other approaches to consider for performant monitoring
beyond the scope of this setting.
* NOTE: Most modern Windows file access APIs do not update file
modification time while the file is open and being actively written to.
Windows delays updating modification time until the file is closed.
Therefore you might have to choose a larger time window on Windows
hosts where files may be open for long time periods.
* Value must be: <number><unit>. For example, "7d" indicates one week.
* Valid units are "d" (days), "h" (hours), "m" (minutes), and "s"
(seconds).
* No default, meaning there is no threshold and no files are
ignored for modification time reasons
followTail = <boolean>
* Whether or not the input should skip past current data in a monitored file
for a given input stanza.
* This setting lets you skip over data in files, and immediately begin indexing
current data.
* If you set to "1", monitoring starts at the end of the file (like
*nix 'tail -f'). The input does not read any data that exists in
the file when it is first encountered. The input only reads data that
arrives after the first encounter time.
* If you set to "0", monitoring starts at the beginning of the file.
* This is an advanced setting. Contact Splunk Support before using it.
* Best practice for using this setting:
* Enable this setting and start the Splunk instance.
* Wait enough time for the input to identify the related files.
* Disable the setting and restart the instance.
* Do not leave 'followTail' enabled in an ongoing fashion.
* Do not use 'followTail' for rolling log files (log files that get renamed as
they age) or files whose names or paths vary.
* Default: 0
alwaysOpenFile = <boolean>
* Whether or not an input opens a file to check whether it has already
been indexed, by skipping the modification time and size checks.
* Only useful for files that do not update modification time or size.
* Only known to be needed when monitoring files on Windows, mostly for
Internet Information Server logs.
* Configuring this setting to "1" can increase load and slow indexing. Use it
only as a last resort.
* Default: 0
time_before_close = <integer>
* The amount of time, in seconds, that the file monitor must wait for
modifications before closing a file after reaching an End-of-File
(EOF) marker.
* Tells the input not to close files that have been updated in the
past 'time_before_close' seconds.
* Default: 3
multiline_event_extra_waittime = <boolean>
* Whether or not the file monitor input delays sending an event delimiter when
it reads a file with multiple-line events, to account for the time it
sometimes takes for lines of those events to arrive.
* By default, the file monitor sends an event delimiter when:
* It reaches EOF of a file it monitors and
* The last character it reads is a newline.
* In some cases, it takes time for all lines of a multiple-line event to
arrive.
* Set to "true" to delay sending an event delimiter until the time that the
file monitor closes the file, as defined by the 'time_before_close' setting,
to allow all event lines to arrive.
* Default: false
recursive = <boolean>
* Whether or not the input monitors subdirectories that it finds within a
monitored directory.
* A value of "true" means the input monitors sub-directories.
* A value of "false" means the input does not monitor sub-directories.
* Default: true
followSymlink = <boolean>
* Whether or not the input follows any symbolic links within a monitored directory.
* A value of "true" means the input follows symbolic links
and monitors files at the symbolic link destination.
* Additionally, any allow lists or deny lists that the input stanza defines
also apply to files at the symbolic link destination.
* A value of "false" means the input ignores symbolic links
that it finds within a monitored directory.
* Default: true
_whitelist = ...
* DEPRECATED.
* This setting is valid unless the 'whitelist' setting also exists.
_blacklist = ...
* DEPRECATED.
* This setting is valid unless the 'blacklist' setting also exists.
BATCH ("Upload a file" in Splunk Web):
Use the 'batch' input for large archives of historic data. If you want to continuously monitor a directory or index small archives, use 'monitor' (see the MONITOR section). 'batch' reads in the file and indexes it, and then deletes the file on disk. [batch://<path>] * A one-time, destructive input of files in <path>. * This stanza must include the 'move_policy = sinkhole' setting. * This input reads and indexes the files, then DELETES THEM IMMEDIATELY. * For continuous, non-destructive inputs of files, use 'monitor' instead. # Additional settings: move_policy = sinkhole * This setting is required. You *must* include "move_policy = sinkhole" when you define batch inputs. * This setting causes the input to load the file destructively. * CAUTION: Do not use the 'batch' input type for files you do not want to delete after indexing. * The 'move_policy' setting exists for historical reasons, but remains as a safeguard. As an administrator, you must explicitly declare that you want the data in the monitored directory (and its sub-directories) to be deleted after being read and indexed. host_regex = see the definition in the MONITOR section. host_segment = see the definition in the MONITOR section. crcSalt = see the definition in the MONITOR section. time_before_close = see the definition in the MONITOR section. log_on_completion = <boolean> * Whether or not the Splunk platform writes an entry into the splunkd.log file when it indexes files with this input. * When set to "false", this setting prevents the Splunk platform from writing to splunkd.log when it indexes files with this input. * Default: true # 'batch' inputs do not use the following setting: # source = <string> followSymlink = <boolean> * Works similarly to the same setting for monitor, but does not delete files after following a symbolic link out of the monitored directory. # The following settings work identically as for [monitor::] stanzas, # documented previously host_regex = <regular expression> host_segment = <integer> crcSalt = <string> recursive = <boolean> whitelist = <regular expression> blacklist = <regular expression> initCrcLength = <integer> time_before_close = <integer>
TCP: Transport Control Protocol (TCP) network inputs
[tcp://<remote server>:<port>]
* Configures the input to listen on a specific TCP network port.
* If a <remote server> makes a connection to this instance, the input uses this
stanza to configure itself.
* If you do not specify <remote server>, this stanza matches all connections
on the specified network port.
* Generates events with source set to "tcp:<port>", for example: tcp:514
* If you do not specify a sourcetype, the input generates events with sourcetype
set to "tcp-raw".
# Additional settings:
connection_host = [ip|dns|none]
* How the network input sets the host field for the events it generates.
* A value of "ip" sets the host to the IP address of the system sending the data.
* A value of "dns" sets the host to the reverse DNS entry for the IP address of
the system that sends the data. For this to work correctly, set the forward
DNS lookup to match the reverse DNS lookup in your DNS configuration.
* A value of "none" leaves the host as specified in inputs.conf, typically the
hostname of the system running Splunk software.
* Default: dns
queueSize = <integer>[KB|MB|GB]
* The maximum size of the in-memory input queue.
* Default: 500KB
persistentQueueSize = <integer>[KB|MB|GB|TB]
* The maximum size of the persistent queue file.
* Persistent queues can help prevent loss of transient data. For information on
persistent queues and how the 'queueSize' and 'persistentQueueSize' settings
interact, search the online documentation for "persistent queues".
* If you set this to a value other than 0, then 'persistentQueueSize' must
be larger than either the in-memory queue size (as defined by the 'queueSize'
setting in inputs.conf or 'maxSize' settings in [queue] stanzas in
server.conf).
* Default: 0 (no persistent queue)
requireHeader = <boolean>
* Whether or not to require a header be present at the beginning of every
stream.
* This header can be used to override indexing settings.
* Default: false
listenOnIPv6 = [no|yes|only]
* Whether or not the input listens on IPv4, IPv6, or both protocols.
* Set to "yes" to listen on both IPv4 and IPv6 protocols.
* Set to "only" to listen on only the IPv6 protocol.
* Default: The setting in the [general] stanza of the server.conf file
acceptFrom = <comma- or space-separated list>
* A list of TCP networks or addresses to accept connections from.
* Use commas or spaces to separate multiple network rules.
* The accepted formats for network and address rules are:
1. A single IPv4 or IPv6 address (examples: "192.0.2.3", "2001:db8::2:1")
2. A Classless Inter-Domain Routing (CIDR) block of addresses
(examples: "192.0.2/24", "2001:DB8::/32")
3. A DNS name. Use "*" as a wildcard.
(examples: "myhost.example.com", "*.example.org")
4. The wildcard "*" matches anything.
* A prefix of '!' for an entry sets a rule to deny and reject connections. The ACL
applies rules in order, and uses the first matching rule. For example,
the rules "!192.0.2/24, *" prevents connections from the 192.0.2/24
network, but accepts all other connections.
* Default: * (accept from anywhere)
rawTcpDoneTimeout = <seconds>
* The amount of time, in seconds, that a network connection can remain idle
before Splunk software declares that the last event over that connection
has been received.
* If a connection over this port remains idle for more than
'rawTcpDoneTimeout' seconds after receiving data, it adds a Done-key. This
declares that the last event has been completely received.
* Default: 10
[tcp:<port>]
* Configures the input listen on the specified TCP network port.
* This stanza is similar to [tcp://<remote server>:<port>], but listens for
connections to the specified port from any host.
* Generates events with a source of tcp:<port>.
* If you do not specify a sourcetype, generates events with a source type of
tcp-raw.
* This stanza supports the following settings:
connection_host = [ip|dns|none]
queueSize = <integer>[KB|MB|GB]
persistentQueueSize = <integer>[KB|MB|GB|TB]
requireHeader = <boolean>
listenOnIPv6 = [no|yes|only]
acceptFrom = <comma- or space-separated list>
rawTcpDoneTimeout = <integer>
Data distribution:
# Global settings for splunktcp. Used on the receiving side for data forwarded
# from a forwarder.
[splunktcp]
route = [has_key|absent_key:<key>:<queueName>;...]
* Settings for the light forwarder.
* The receiver sets these parameters automatically -- you do not need to set
them yourself.
* The property route is composed of rules delimited by ';' (semicolon).
* The receiver checks each incoming data payload through the cooked TCP port
against the route rules.
* If a matching rule is found, the receiver sends the payload to the specified
<queueName>.
* If no matching rule is found, the receiver sends the payload to the default
queue specified by any queue= for this stanza. If no queue= key is set in
the stanza or globally, the receiver sends the events to the parsingQueue.
enableS2SHeartbeat = <boolean>
* Specifies the global keepalive setting for all splunktcp ports.
* This option is used to detect forwarders which might have become unavailable
due to network, firewall, or other problems.
* The receiver monitors each connection for presence of a heartbeat, and if the
heartbeat is not seen for 's2sHeartbeatTimeout' seconds, it closes the
connection.
* Default: true (heartbeat monitoring enabled)
s2sHeartbeatTimeout = <integer>
* The amount of time, in seconds, that a receiver waits for heartbeats from
forwarders that connect to this instance.
* The receiver closes a forwarder connection if it does not receive
a heartbeat for 's2sHeartbeatTimeout' seconds.
* Default: 600 (10 minutes)
inputShutdownTimeout = <integer>
* The amount of time, in seconds, that a receiver waits before shutting down
inbound TCP connections after it receives a signal to shut down.
* Used during shutdown to minimize data loss when forwarders are connected to a
receiver.
* During shutdown, the TCP input processor waits for 'inputShutdownTimeout'
seconds and then closes any remaining open connections.
* If all connections close before the end of the timeout period,
shutdown proceeds immediately, without waiting for the timeout.
stopAcceptorAfterQBlock = <integer>
* The amount of time, in seconds, to wait before closing the splunktcp port.
* If the receiver is unable to insert received data into the configured queue
for more than the specified number of seconds, it closes the splunktcp port.
* This action prevents forwarders from establishing new connections to this
receiver.
* Forwarders that have an existing connection will notice the port is closed
upon test-connections and move to other receivers.
* After the queue unblocks, and the TCP input can continue processing data, the
receiver starts listening on the port again.
* This setting should not be adjusted lightly as extreme values can interact
poorly with other defaults.
* NOTE: If there are multiple tcp/splunktcp listener ports configured,
all listening ports will be shut down regardless of whether other queues are
blocked or not.
* Default: 300 (5 minutes)
listenOnIPv6 = no|yes|only
* See the description for this setting in the [tcp://<remote server>:<port>]
stanza.
acceptFrom = <comma- or space-separated list>
* See the description for this setting in the [tcp://<remote server>:<port>]
stanza.
negotiateProtocolLevel = <unsigned integer>
* If set, lets forwarders that connect to this receiver (or specific port)
send data using only up to the specified feature level of the Splunk
forwarder protocol.
* If set to a value that is lower than the default, denies the use
of newer forwarder protocol features during connection negotiation. This
might impact indexer efficiency.
* Default (if 'negotiateNewProtocol' is "true"): 1
* Default (if 'negotiateNewProtocol' is not "true"): 0
negotiateNewProtocol = <boolean>
* DEPRECATED.
* Use the 'negotiateProtocolLevel' setting instead.
* Controls the default configuration of the 'negotiateProtocolLevel' setting.
* Default: true
concurrentChannelLimit = <unsigned integer>
* The number of unique channel codes that are available for forwarders to
use to communicate with an indexer.
* Each forwarder that connects to this indexer may use up to
'concurrentChannelLimit' unique channel codes.
* In other words, each forwarder may have up to 'concurrentChannelLimit'
channels in flight concurrently.
* The receiver closes a forwarder connection if a forwarder attempts to
exceed this value.
* This setting only applies when the new forwarder protocol is in use.
* Default: 300
logRetireOldS2S = <boolean>
* Whether or not the Splunk platform logs the usage of old versions of Splunk-to-Splunk (S2S)
protocol.
* The old S2S protocol retirement logs provide visibility into customers' usage
of the old S2S protocol version V3 which is less performant than the current version V4.
* A value of "true" means that splunkd generates warning logs for the old S2S protocol
versions.
* See the 'logRetireOldS2SRepeatFrequency' setting for additional constraints on
when the Splunk platform logs the use of old S2S protocol versions.
* Default: true
logRetireOldS2SMaxCache = <unsigned integer>
* The size of the cache for tracking forwarders that use old S2S protocols.
* The cache keeps track of unique forwarders that use the old S2S protocol. When a
forwarder is in the cache, the Splunk platform doesn't log usage of the old protocol
for that forwarder for a time period of 'logRetireOldS2SRepeatFrequency', to avoid generating
duplicate logs.
* If the cache fills before the 'logRetireOldS2SRepeatFrequency' period elapses,
the Splunk platform removes the forwarder that has been in the cache the longest
from the cache to make space.
* Update this setting as per the number of forwarders that currently use the old S2S
protocol to send data to indexers. If the number of forwarders that use
old S2S protocols is larger than the cache size, some forwarders might generate duplicate
logs even though the previous log was within the 'logRetireOldS2SRepeatFrequency'
period.
* When you restart Splunk Enterprise, the cache resets and the timer starts over.
* This setting takes effect only when 'logRetireOldS2S' has a value of "true".
* Default: 10000
logRetireOldS2SRepeatFrequency = <timespan>
* The interval between writing repeat entries into the retire old S2S warning log
for a certain forwarder.
* This setting helps reduce retire old S2S log size by providing control over how
often to log.
* When a forwarder uses the old S2S protocol version to communicate with splunkd, splunkd
adds the forwarder to a cache. Subsequent communication with the same
forwarder won't generate a new entry to the log until a period of
'logRetireOldS2SRepeatFrequency' has elapsed. Splunkd then resets the log timestamp and
writes another "retire old S2S protocol" warning log entry.
* The Splunk platform enforces this setting as long as the size of the cache
does not exceed 'logRetireOldS2SMaxCache' entries. When there are more than
'logRetireOldS2SMaxCache' entries, the cache removes the entry with the oldest
access time to make space.
* When you restart Splunk Enterprise, the cache resets and the timer starts over.
* This setting takes effect only when 'logRetireOldS2S' has a value of "true".
* A value of "0" means that the platform logs old S2S protocol warning entries every time
it receives a communication using the old S2S protocol version.
* Default: 1d
# Forwarder-specific settings for splunktcp.
[splunktcp://[<remote server>]:<port>]
* Receivers use this input stanza.
* This is the same as the [tcp://] stanza, except the remote server is assumed
to be a Splunk instance, most likely a forwarder.
* <remote server> is optional. If you specify it, the receiver listens only for
data from <remote server>.
* Use of <remote server> is not recommended. Use the 'acceptFrom' setting,
which supersedes this setting.
connection_host = [ip|dns|none]
* For splunktcp, the 'host' or 'connection_host' is be used if the remote
Splunk instance does not set a host, or if the host is set to
"<host>::<localhost>".
* "ip" sets the host to the IP address of the system sending the data.
* "dns" sets the host to the reverse DNS entry for IP address of the system
that sends the data. For this to work correctly, set the forward DNS lookup
to match the reverse DNS lookup in your DNS configuration.
* "none" leaves the host as specified in inputs.conf, typically the Splunk
system hostname.
* Default: ip
compressed = <boolean>
* Whether or not the receiver communicates with the forwarder in
compressed format.
* Applies to non-Secure Sockets Layer (SSL) receiving only. There is no
compression setting required for SSL.
* A value of "true" means the receiver communicates with the forwarder in
compressed format.
* If set to "true", there is no longer a requirement to also set
"compressed = true" in the outputs.conf file on the forwarder.
* Default: false
enableS2SHeartbeat = <boolean>
* Specifies the keepalive setting for the splunktcp port.
* This option is used to detect forwarders which might have become unavailable
due to network, firewall, or other problems.
* The receiver monitors the connection for presence of a heartbeat, and if it
does not see the heartbeat in 's2sHeartbeatTimeout' seconds, it closes the
connection.
* This overrides the default value specified at the global [splunktcp] stanza.
* Default: true (heartbeat monitoring enabled)
s2sHeartbeatTimeout = <integer>
* The amount of time, in seconds, that a receiver waits for heartbeats from
forwarders that connect to this instance.
* The receiver closes the forwarder connection if it does not see a heartbeat
for 's2sHeartbeatTimeout' seconds.
* This overrides the default value specified at the global [splunktcp] stanza.
* Default: 600 (10 minutes)
queueSize = <integer>[KB|MB|GB]
* The maximum size of the in-memory input queue.
* Default: 500KB
negotiateProtocolLevel = <unsigned integer>
* See the description for this setting in the [splunktcp] stanza.
negotiateNewProtocol = <boolean>
* See the description for this setting in the [splunktcp] stanza.
concurrentChannelLimit = <unsigned integer>
* See the description for this setting in the [splunktcp] stanza.
[splunktcp:<port>]
* This input stanza is the same as [splunktcp://[<remote server>]:<port>], but
the input accepts connections from any server.
* See the online documentation for [splunktcp://[<remote server>]:<port>] for
more information on the following supported settings:
connection_host = [ip|dns|none]
compressed = <boolean>
enableS2SHeartbeat = <boolean>
s2sHeartbeatTimeout = <integer>
queueSize = <integer>[KB|MB|GB]
negotiateProtocolLevel = <unsigned integer>
negotiateNewProtocol = <boolean>
concurrentChannelLimit = <unsigned integer>
# Access control settings.
[splunktcptoken://<token name>]
* Use this stanza to specify forwarders from which to accept data.
* You must configure a token on the receiver, then configure the same
token on forwarders.
* The receiver discards data from forwarders that do not have the
token configured.
* This setting is enabled for all receiving ports.
* This setting is optional.
* NOTE: When specifying a <token name>, you must use a specific format,
as follows: NNNNNNNN-NNNN-NNNN-NNNN-NNNNNNNNNNNN. Failure to use this
format results in the token being ignored.
* For example, 'A843001F-B2B5-4F94-847D-D07802685BB2'
token = <string>
* The value of the token.
* Must be in the format NNNNNNNN-NNNN-NNNN-NNNN-NNNNNNNNNNNN. Failure to
use this string format results in the token being ignored.
# SSL settings for data distribution:
[splunktcp-ssl:<port>]
* Use this stanza type if you are receiving encrypted, parsed data from a
forwarder.
* Set <port> to the port on which the forwarder sends the encrypted data.
* Forwarder settings are set in outputs.conf on the forwarder.
* Compression for SSL is enabled by default. On the forwarder you can still
specify compression with the 'useClientSSLCompression' setting in
outputs.conf.
* The 'compressed' setting is used for non-SSL connections. However, if you
still specify 'compressed' for SSL, ensure that the 'compressed' setting is
the same as on the forwarder, as splunktcp protocol expects the same
'compressed' setting from forwarders.
connection_host = [ip|dns|none]
* See the description for this setting in the [splunktcp:<port>] stanza.
* Default: ip

* Set <port> to the port on which the forwarder/third-party system is sending
unparsed, encrypted data.
* To create multiple SSL inputs, you can add the following attributes to each

Subsequent connections with the same certificate won't generate a new entry to the log until a period of 'certLogRepeatFrequency' has passed. After this amount of time elapses, splunkd resets the log timestamp and writes another certificate log entry. * The Splunk platform enforces this setting as long as the size of the cache does not reach 'certLogMaxCacheEntries'. When there are more than 'certLogMaxCacheEntries', the cache removes the entry with the oldest access time to make space. * When you restart Splunk Enterprise, the cache resets and the timer starts over. * This setting takes effect only when 'logCertificateData' has a value of 'true'. * A value of "0" means that the platform logs certificate data every time it receives a certificate. * Default: 1d sslCommonNameToCheck = <comma-separated list> * Checks the common name of the client certificate against this list of names. * If there is no match, assumes that the Splunk instance is not authenticated against this server. * For this setting to work, you must also set 'requireClientCert' to "true". * This setting is optional. * Default: empty string (no common name checking) sslAltNameToCheck = <comma-separated list> * Checks the alternate name of the client certificate against this list of names. * If there is no match, assumes that the Splunk instance is not authenticated against this server. * For this setting to work, you must also set 'requireClientCert' to "true". * This setting is optional. * Default: empty string (no alternate name checking) useSSLCompression = <boolean> * Whether or not the server lets forwarders that connect to it negotiate SSL- layer data compression. * A value of "true" means the server lets forwarders negotiate SSL-layer data compression. * Default: The value of 'server.conf/[sslConfig]/allowSslCompression' sslServerHandshakeTimeout = <integer> * The timeout, in seconds, for an SSL handshake to complete between forwarder and the TCP input processor. * If the TCP input processor does not receive a "Client Hello" from the forwarder within 'sslServerHandshakeTimeout' seconds, the server terminates the connection. * Default: 60
UDP (User Datagram Protocol network input):
[udp://<remote server>:<port>]
* Similar to the [tcp://] stanza, except that this stanza causes the Splunk
instance to listen on a UDP port.
* Only one stanza per port number is currently supported.
* Configures the instance to listen on a specific port.
* If you specify <remote server>, the specified port only accepts data
from that host.
* If <remote server> is empty - [udp://<port>] - the port accepts data sent
from any host.
* The use of <remote server> is not recommended. Use the 'acceptFrom'
setting, which supersedes this setting.
* Generates events with source set to udp:portnumber, for example: udp:514
* If you do not specify a sourcetype, generates events with sourcetype set
to udp:portnumber.
# Additional settings:
connection_host = [ip|dns|none]
* "ip" sets the host to the IP address of the system sending the data.
* "dns" sets the host to the reverse DNS entry for IP address of the system
that sends the data. For this to work correctly, set the forward DNS lookup
to match the reverse DNS lookup in your DNS configuration.
* "none" leaves the host as specified in inputs.conf, typically the Splunk
system hostname.
* If the input is configured with a 'sourcetype' that has a transform that
overrides the 'host' field e.g. 'sourcetype=syslog', that takes
precedence over the host specified here.
* Default: ip
_rcvbuf = <integer>
* The receive buffer, in bytes, for the UDP port.
* If you set the value to 0 or a negative number, the input ignores the value.
* If the default value is too large for an OS, the instance tries to set
the value to 1572864/2. If that value is also too large, the instance
retries with 1572864/(2*2). It continues to retry by halving the value until
it succeeds.
* Default: 1572864
no_priority_stripping = <boolean>
* Whether or not the input strips <priority> syslog fields from events it
receives over the syslog input.
* A value of "true" means the instance does NOT strip the <priority>
syslog field from received events.
* NOTE: Do NOT set this setting if you want to strip <priority>.
* Default: false
no_appending_timestamp = <boolean>
* Whether or not to append a timestamp and host to received events.
* A value of "true" means the instance does NOT append a timestamp
and host to received events.
* NOTE: Do NOT set this setting if you want to append timestamp and host
to received events.
* Default: false
queueSize = <integer>[KB|MB|GB]
* The maximum size of the in-memory input queue.
* Default: 500KB
persistentQueueSize = <integer>[KB|MB|GB|TB]
* The maximum size of the persistent queue file.
* Persistent queues can help prevent loss of transient data. For information on
persistent queues and how the 'queueSize' and 'persistentQueueSize' settings
interact, search the online documentation for "persistent queues"..
* If you set this to a value other than 0, then 'persistentQueueSize' must
be larger than either the in-memory queue size (as defined by the 'queueSize'
setting in inputs.conf or 'maxSize' settings in [queue] stanzas in
server.conf).
* Default: 0 (no persistent queue)
listenOnIPv6 = [no|yes|only]
* Select whether the instance listens on the IPv4, IPv6, or both protocols.
* Set this to 'yes' to listen on both IPv4 and IPv6 protocols.
* Set to 'only' to listen on only the IPv6 protocol.
* If not present, the input uses the setting in the [general] stanza
of server.conf.
acceptFrom = <comma- or space-separated list>
* See the description for this setting in the [tcp://<remote server>:<port>]
stanza.
* Default: "*" (accept from anywhere)
[udp:<port>]
* This input stanza is the same as [udp://<remote server>:<port>], but does
not have a <remote server> restriction.
* See the documentation for [udp://<remote server>:<port>] to configure
supported settings:
connection_host = [ip|dns|none]
_rcvbuf = <integer>
no_priority_stripping = <boolean>
no_appending_timestamp = <boolean>
queueSize = <integer>[KB|MB|GB]
persistentQueueSize = <integer>[KB|MB|GB|TB]
listenOnIPv6 = <no | yes | only>
acceptFrom = <comma- or space-separated list>
FIFO (First In, First Out queue):
[fifo://<path>] * This stanza configures the monitoring of a FIFO at the specified path. queueSize = <integer>[KB|MB|GB] * Maximum size of the in-memory input queue. * Default: 500KB persistentQueueSize = <integer>[KB|MB|GB|TB] * Maximum size of the persistent queue file. * Persistent queues can help prevent loss of transient data. For information on persistent queues and how the 'queueSize' and 'persistentQueueSize' settings interact, search the online documentation for "persistent queues".. * If you set this to a value other than 0, then 'persistentQueueSize' must be larger than either the in-memory queue size (as defined by the 'queueSize' setting in inputs.conf or 'maxSize' settings in [queue] stanzas in server.conf). * Default: 0 (no persistent queue)
Scripted Input:
[script://<cmd>]
* Runs <cmd> at a configured interval and indexes the output
that <cmd> returns.
* To determine the interval at which the input runs <cmd>,
use the 'interval' setting.
* The <cmd> must reside in one of the following directories:
* $SPLUNK_HOME/etc/system/bin/
* $SPLUNK_HOME/etc/apps/$<APPNAME>/bin/
* $SPLUNK_HOME/bin/scripts/
* The path to <cmd> can be an absolute path, make use of an environment
variable such as $SPLUNK_HOME, or use the special pattern of an initial '.'
as the first directory to indicate a location inside the current app.
For more scripted input examples, search the documentation for
"Add a scripted input with inputs.conf."
* <cmd> can also be a path to a file that ends with a ".path" suffix. A file
with this suffix is a special type of pointer file that points to a command
to be run. Although the pointer file is bound by the same location
restrictions mentioned previously, the command referenced inside it can
reside anywhere on the file system. The .path file must contain exactly
one line: the path to the command to run, optionally followed by command-line
arguments. The file can contain additional empty lines and lines that begin
with '#'. The input ignores these lines.
interval = [<decimal>|<cron schedule>]
* How often, in seconds, to run the specified command, or a valid "cron"
schedule.
* If you specify the interval as a number, it may have a fractional
component; for example, 3.14
* To specify a cron schedule, use the following format:
* "<minute> <hour> <day of month> <month> <day of week>"
* Cron special characters are acceptable. You can use combinations of "*",
",", "/", and "-" to specify wildcards, separate values, specify ranges
of values, and step values.
* The cron implementation for data inputs does not currently support names
of months or days.
* The special value "0" forces this scripted input to be run continuously.
As soon as the script exits, the input restarts it.
* The special value "-1" causes the scripted input to run once on start-up.
* NOTE: when you specify a cron schedule, the input does not run the
script on start-up.
* Default: 60.0
passAuth = <string>
* The user to run the script as.
* If you provide a username, the instance generates an auth token for that
user and passes it to the script through the stdin data stream.
* No default.
python.version = [default|python|python2|python3]
* For Python scripts only, selects which Python version to use.
* Set to either "default" or "python" to use the system-wide default Python
version.
* Optional.
* Default: Not set; uses the system-wide Python version.
queueSize = <integer>[KB|MB|GB]
* Maximum size of the in-memory input queue.
* Default: 500KB
persistentQueueSize = <integer>[KB|MB|GB|TB]
* Maximum size of the persistent queue file.
* Persistent queues can help prevent loss of transient data. For information on
persistent queues and how the 'queueSize' and 'persistentQueueSize' settings
interact, search the online documentation for "persistent queues"..
* If you set this to a value other than 0, then 'persistentQueueSize' must
be larger than either the in-memory queue size (as defined by the 'queueSize'
setting in inputs.conf or 'maxSize' settings in [queue] stanzas in
server.conf).
* Default: 0 (no persistent queue)
index = <string>
* The index where the scripted input sends the data.
* The script passes this parameter as a command-line argument to <cmd> in
the format: -index <index name>.
If the script does not need the index info, it can ignore this argument.
* If you do not specify an index, the script uses the default index.
send_index_as_argument_for_path = <boolean>
* Whether or not to pass the index as an argument when specified for
stanzas that begin with 'script://'
* A value of "true" means the script passes the argument as
'-index <index name>'.
* To avoid passing the index as a command line argument, set this to "false".
* Default: true
start_by_shell = <boolean>
* Whether or not to run the specified command through the operating system
shell or command prompt.
* A value of "true" means the host operating system runs the
specified command through the OS shell ("/bin/sh -c" on *NIX,
"cmd.exe /c" on Windows.)
* A value of "false" means the input runs the program directly
without attempting to expand shell metacharacters.
* You might want to explicitly set a value of "false" for scripts
that you know do not need UNIX shell metacharacter expansion. This is
a Splunk best practice.
* Default (on *nix machines): true
* Default (on Windows machines): false
File system change monitor (fschange monitor)
#
# The file system change monitor has been deprecated as of Splunk Enterprise
# version 5.0 and might be removed in a future version of the product.
#
# You cannot simultaneously monitor a directory with both the 'fschange'
# and 'monitor' stanza types.
#
[fschange:<path>]
* Monitors changes (such as additions, updates, and deletions) to this
directory and any of its sub-directories.
* <path> is the direct path. Do not preface it with '//' like with
other inputs.
* Sends an event for every change.
disabled = <boolean>
* Whether or not the file system change monitor input is active.
* Set a value of "true" to disable the input, and "false" to enable it.
* Default: false
# Additional settings:
# NOTE: The 'fschange' stanza type does not use the same settings as
# other input types. It uses only the following settings:
index = <string>
* The index where the input sends the data.

set 'signedaudit' to "false"): _audit
* Default: (in all other cases): the default index
signedaudit = <boolean>
* Whether or not to send cryptographically signed add/update/delete events.
* A value of "true" means the input does the following to
events that it generates:
* Puts the events in the _audit index.
* Sets the event sourcetype to 'audittrail'
* A value of "false" means the input:
* Places events in the default index.
* Sets the sourcetype to whatever you specify (or "fs_notification"
by default).
* You must set 'signedaudit' to "false" if you want to set the index for
fschange events.
* You must also enable auditing by using the audit.conf file.
* Default: false
filters = <comma-separated list>
* The fschange input applies each filter, left to right, for each file
or directory found during the monitor poll cycle.
* See the "File System Monitoring Filters" section later in this file
for help on how to define a fschange filter.
recurse = <boolean>
* Whether or not the fschange input should look through all sub-directories
for changes to files in a directory.
* A value of "true" means the input searches recursively through
sub-directories within the directory specified in [fschange].
* Default: true
followLinks = <boolean>
* Whether or not the fschange input follows any symbolic
links it encounters.
* A value of "true" means the input follows symbolic links.
* CAUTION: Do not set this setting to "true" unless you can confirm that
doing so will not create a file system loop (For example, in
Directory A, symbolic link B points back to Directory A.)
* Default: false
pollPeriod = <integer>
* How often, in seconds, to check a directory for changes.
* Default: 3600 (1 hour)
hashMaxSize = <integer>
* The maximum size, in bytes, that a file can be for the fschange input to
calculate a SHA256 hash for that file.
* Tells the fschange input to calculate a SHA256 hash for every file that
is this size or smaller, in bytes.

file or directory.
* Default: -1 (disabled)
fullEvent = <boolean>
* Whether or not to send the full event if the input detects an add or
update change.
* Set to "true" to send the full event if an add or update change is detected.
* Further qualified by the 'sendEventMaxSize' setting.
* Default: false
sendEventMaxSize = <integer>
* The maximum size, in bytes, that an fschange event can be for the input to
send the full event to be indexed.
* Limits the size of event data that the fschange input sends.
* This also limits the size of indexed file data.
* Default: -1 (unlimited)
sourcetype = <string>
* Sets the source type for events from this input.
* The input automatically prepends "sourcetype=" to <string>.
* Default (if you set the 'signedaudit' setting to "true"): audittrail
* Default (if you set the 'signedaudit' setting to "false"): fs_notification
host = <string>
* Sets the host name for events from this input.
* Default: whatever host sent the event
filesPerDelay = <integer>
* The number of files that the fschange input processes between processing
delays, as specified by the 'delayInMills' setting.
* After a delay of 'delayInMills' milliseconds, the fschange input processes
'filesPerDelay' files, then waits 'delayInMills' milliseconds again before
repeating this process.
* This setting helps throttle file system monitoring so it consumes less CPU.
* Default: 10
delayInMills = <integer>
* The delay, in milliseconds, that the fschange input waits between
processing 'filesPerDelay' files.
* After a delay of 'delayInMills' milliseconds, the fschange input processes
'filesPerDelay' files, then waits 'delayInMills' milliseconds again before
repeating this process.
* This setting helps throttle file system monitoring so it consumes less CPU.
* Default: 100
File system monitoring filters:
[filter:<filtertype>:<filtername>]
* Defines a filter of type <filtertype> and names it <filtername>.
* <filtertype>:
* Filter types are either 'blacklist' or 'whitelist.' 'blacklist' is the
deny list filter type and 'whitelist' is the allow list filter type.
* An allow list filter processes all file names that match the
regular expression list that you define within the stanza.
* A deny list filter skips all file names that match the
regular expression list.
* <filtername>
* The fschange input uses filter names that you specify with
the 'filters' setting for a given fschange stanza.
* You can specify multiple filters by separating them with commas.
regex<integer> = <regular expression>
* Deny list and allow list filters can include a set of regular expressions.
* The name of each regular expression MUST be 'regex<integer>', meaning the
string "regex" and then an integer. <integer> starts at 1 and increments by 1.
* The input applies each regular expression in numeric order:

to this directory for the configuration to work.
* When enabled, only the tokens defined in the splunk_httpinput app in this
repository are viewable and editable through the API and Splunk Web.
* When disabled, the input writes its configuration to
$SPLUNK_HOME/etc/apps by default.
* Default: 0 (disabled)
index = <string>
* The default index to use.
* Default: the "default" index
sourcetype = <string>
* The default source type for the events that the input generates.
* If you do not specify a sourcetype, the input does not set a sourcetype
for events it generates.

* HEC shares SSL settings with the Splunk management server and cannot have
SSL enabled when the Splunk management server has SSL disabled.
* Default: 1 (enabled)
dedicatedIoThreads = <non-negative integer>
* The number of dedicated input/output threads in the event collector
input.
* Default: 0 (The input uses a single thread)
replyHeader.<name> = <string>
* Adds a static header to all HTTP responses that this server generates.
* For example, "replyHeader.My-Header = value" causes the
response header "My-Header: value" to be included in the reply to
every HTTP request made to the event collector endpoint server.
* No default.
maxSockets = <integer>
* The number of HTTP connections that the HTTP event collector input
accepts simultaneously.
* Set this setting to constrain resource usage.
* If you set this setting to 0, the input automatically sets it to
one third of the maximum allowable open files on the host.
* If this value is less than 50, the input sets it to 50. If this value
is greater than 400000, the input sets it to 400000.
* If set to a negative value, the input does not enforce a limit on
connections.
* Default: 0
maxThreads = <integer>
* The number of threads that can be used by active HTTP transactions.
* Set this to constrain resource usage.
* If you set this setting to 0, the input automatically sets the limit to
one third of the maximum allowable threads on the host.
* If this value is less than 20, the input sets it to 20. If this value is
greater than 150000, the input sets it to 150000.
* If the 'maxSockets' setting has a positive value and 'maxThreads'
is greater than 'maxSockets', then the input sets 'maxThreads' to be equal
to 'maxSockets'.
* If set to a negative value, the input does not enforce a limit on threads.
* Default: 0
keepAliveIdleTimeout = <integer>
* How long, in seconds, that the HTTP Event Collector input lets a keep-alive
connection remain idle before forcibly disconnecting it.

* Default: 7200
busyKeepAliveIdleTimeout = <integer>
* How long, in seconds, that the HTTP Event Collector lets a keep-alive
connection remain idle while in a busy state before forcibly disconnecting it.
* CAUTION: Setting this to a value that is too large
can result in file descriptor exhaustion due to idling connections.
* If this value is less than 12, the input sets it to 12.
* Default: 12
serverCert = <string>
* The full path to the server certificate PEM format file.
* The same file may also contain a private key.
* Splunk software automatically generates certificates when it first
starts.
* You may replace the auto-generated certificate with your own certificate.
* Default: $SPLUNK_HOME/etc/auth/server.pem
sslKeysfile = <string>
* DEPRECATED.
* Use the 'serverCert' setting instead.
* The file that contains the SSL keys. Splunk software looks for this file
in the directory specified by 'caPath'.
* Default: server.pem
sslPassword = <string>
* The server certificate password.
* Initially set to a plain-text password.
* Upon first use, Splunk software encrypts and rewrites the password.
* Default: password
sslKeysfilePassword = <string>
* DEPRECATED.
* Use the 'sslPassword' setting instead.
caCertFile = <string>
* DEPRECATED.
* Use the 'server.conf:[sslConfig]/sslRootCAPath' setting instead.
* Used only if you do not set the 'sslRootCAPath' setting.
* Specifies the file name (relative to 'caPath') of the CA
(Certificate Authority) certificate PEM format file that contains one or
more certificates concatenated together.
* Default: cacert.pem
caPath = <string>
* DEPRECATED.
* Use absolute paths for all certificate files.
* If certificate files given by other settings in this stanza are not absolute
paths, then they are relative to this path.
* Default: $SPLUNK_HOME/etc/auth
sslVersions = <comma-separated list>
* A comma-separated list of SSL versions to support.
* The versions available are "ssl3", "tls1.0", "tls1.1", and "tls1.2"
* The special version "*" selects all supported versions. The version "tls"
selects all versions "tls1.0" or newer.
* To remove a version from the list, prefix it with "-".
* SSLv2 is always disabled. Specifying "-ssl2" in the version list
has no effect.
* When configured in Federal Information Processing Standard (FIPS) mode, the
"ssl3" version is always disabled, regardless of this configuration.
* Default: *,-ssl2 (anything newer than SSLv2)
cipherSuite = <string>
* The cipher string to use for the HTTP Event Collector input.
* Use this setting to ensure that the server does not accept connections using
weak encryption protocols.
* If you set this setting, the input uses the specified cipher string for
the HTTP server.
* Default: The default cipher string that 'OpenSSL' provides
sslServerHandshakeTimeout = <integer>
* The timeout, in seconds, for an SSL handshake to complete between an
HEC client and the Splunk HEC server.
* If the HEC server does not receive a "Client Hello" from the HEC client within
'sslServerHandshakeTimeout' seconds, the server terminates
the connection.
* Default: 60
listenOnIPv6 = [no|yes|only]
* Whether or not this input listens on IPv4, IPv6, or both.
* Set to "no" to make the input listen only on the IPv4 protocol.
* Set to "yes" to make the input listen on both IPv4 and IPv6 protocols.
* Set to "only" to make the input listen on only the IPv6 protocol.
* Default: The setting in the [general] stanza of the server.conf file
acceptFrom = <comma- or space-separated list>
* See the description for this setting in the [tcp://<remote server>:<port>]
stanza.
* Default: "*" (accept from anywhere)
requireClientCert = <boolean>
* Requires that any client connecting to the HEC port has a certificate that
can be validated by the certificate authority specified in the
'caCertFile' setting.
* Default: false
ecdhCurveName = <string>
* DEPRECATED.
* Use the 'ecdhCurves' setting instead.
* This setting specifies the ECDH curve to use for ECDH key negotiation.
* Splunk software only supports named curves that have been specified by their
SHORT names.
* The list of valid named curves by their short or long names
can be obtained by executing this command:
$SPLUNK_HOME/bin/splunk cmd openssl ecparam -list_curves
* Default: empty string
ecdhCurves = <comma-separated list>
* ECDH curves to use for ECDH key negotiation.
* The curves should be specified in the order of preference.
* The client sends these curves as a part of Client Hello.
* The server supports only the curves specified in the list.
* Splunk software only supports named curves that have been specified by their
SHORT names.
* The list of valid named curves by their short or long names can be obtained
by executing this command:
$SPLUNK_HOME/bin/splunk cmd openssl ecparam -list_curves
* Example setting: ecdhCurves = prime256v1,secp384r1,secp521r1
* Default: empty string
crossOriginSharingPolicy = <origin_acl> ...
* A list of the HTTP Origins for which to return Access-Control-Allow-*
Cross-origin Resource Sharing (CORS) headers.
* These headers tell browsers that web applications at those sites
can be trusted to make requests to the REST interface.
* The origin is passed as a URL without a path component (for example
"https://app.example.com:8000").
* This setting can take a list of acceptable origins, separated
by spaces and/or commas.
* Each origin can also contain wildcards for any part. Examples:
* *://app.example.com:* (either HTTP or HTTPS on any port)
* https://*.example.com (any host under example.com, including
example.com itself).
* An address can be prefixed with a '!' to negate the match, with
the first matching origin taking precedence. Example:
* "!*://evil.example.com:* *://*.example.com:*" to not avoid
matching one host in a domain.
* "*" matches all origins.
* Default: empty string
crossOriginSharingHeaders = <string>
* A list of the HTTP headers to which splunkd sets
"Access-Control-Allow-Headers" when replying to
Cross-Origin Resource Sharing (CORS) preflight requests.
* The "Access-Control-Allow-Headers" header is used in response to
a CORS preflight request to tell browsers which HTTP headers can be
used during the actual request.
* A CORS preflight request is a CORS request that checks to see if
the CORS protocol is understood and a server is aware of using
specific methods and headers.
* This setting can take a list of acceptable HTTP headers, separated
by commas.
* A single "*" can also be used to match all headers.
* Default: empty string
forceHttp10 = [auto|never|always]
* Whether or not the REST HTTP server forces clients that connect
to it to use the HTTP 1.0 specification for web communications.
* When set to "always", the REST HTTP server does not use some
HTTP 1.1 features such as persistent connections or chunked
transfer encoding.
* When set to "auto", it does this only if the client did not send
a User-Agent header, or if the user agent is known to have bugs
in its support of HTTP/1.1.
* When set to "never" it always allows HTTP 1.1, even to
clients it suspects might be buggy.
* Default: auto
sslCommonNameToCheck = <comma-separated list>
* A list of SSL Common Names to match against certificates that incoming
HTTPS connections present to this instance.
* If you configure this setting and also set 'requireClientCert' to "true",
splunkd limits most inbound HTTPS connections to hosts that use
a cert with one of the listed common names.
* The most important scenario to use this setting is distributed search.
* This feature does not work with the deployment server and client
communication over SSL.
* This setting is optional.
* Default: empty string (no common name checking)
sslAltNameToCheck = <comma-separated list>
* If you set this setting and also set 'requireClientCert' to true,
splunkd can verify certificates that have a so-called
"Subject Alternate Name" that matches any of the alternate
names in this list.
* Subject Alternate Names are effectively extended descriptive
fields in SSL certs beyond the commonName. A common practice for
HTTPS certs is to use these values to store additional valid
hostnames or domains where the cert should be considered valid.
* Accepts a comma-separated list of Subject Alternate Names to consider
valid.
* Items in this list are never validated against the SSL Common Name.
* This feature does not work with the deployment server and client
communication over SSL.
* This setting is optional.
* Default: empty string (no alternate name checking)
sendStrictTransportSecurityHeader = <boolean>
* Whether or not to force inbound connections to always use SSL with
the "Strict-Transport-Security" header..
* If set to "true", the REST interface sends a "Strict-Transport-Security"
header with all responses to requests made over SSL.
* This can help prevent a client being tricked later by a Man-In-The-Middle
attack to accept a non-SSL request. However, this requires a commitment that
no non-SSL web hosts will ever be run on this hostname on any port. For
example, if Splunk Web is in default non-SSL mode this can break the
ability of the browser to connect to it. Enable with caution.
* Default: false
allowSslCompression = <boolean>
* Whether or not to allow data compression over SSL.
* If set to "true", the server allows clients to negotiate
SSL-layer data compression.
* Default: true
allowSslRenegotiation = <boolean>
* Whether or not to let SSL clients renegotiate their connections.
* In the SSL protocol, a client may request renegotiation of the connection
settings from time to time.
* Setting this to false causes the server to reject all renegotiation
attempts, which breaks the connection.
* This limits the amount of CPU a single TCP connection can use, but it can
cause connectivity problems, especially for long-lived connections.
* Default: true
ackIdleCleanup = <boolean>
* Whether or not to remove ACK channels that have been idle after a period
of time, as defined by the 'maxIdleTime' setting.
* A value of "true" means the server removes the ACK channels that are idle
for 'maxIdleTime' seconds.
* Default: true
maxIdleTime = <integer>
* The maximum amount of time, in seconds, that ACK channels can be idle
before they are removed.
* If 'ackIdleCleanup' is "true", the system removes ACK channels that have
been idle for 'maxIdleTime' seconds.
* Default: 600 (10 minutes)
channel_cookie = <string>
* The name of the cookie to use when sending data with a specified channel ID.
* The value of the cookie is the channel sent. For example, if you have
set 'channel_cookie=foo' and sent a request with channel ID set to 'bar',
then you will have a cookie in the response with the value 'foo=bar'.
* If no channel ID is present in the request, then no cookie is returned.
* This setting is to be used for load balancers (for example, AWS ELB) that can
only provide sticky sessions on cookie values and not general header values.
* If no value is set (the default), then no cookie is returned.
* Default: empty string (no cookie)
maxEventSize = <positive integer>[KB|MB|GB]
* The maximum size of a single HEC (HTTP Event Collector) event.
* HEC disregards and triggers a parsing error for events whose size is
greater than 'maxEventSize'.
* Default: 5MB
HTTP Event Collector (HEC) - Local stanza for each token
[http://name]
token = <string>
* The value of the HEC token.
* HEC uses this token to authenticate inbound connections. Your application
or web client must present this token when attempting to connect to HEC.
* No default.
disabled = <boolean>
* Whether or not this token is active.
* Default: 0 (enabled)
description = <string>
* A human-readable description of this token.
* Default: empty string
indexes = <comma-separated list>
* The indexes that events for this token can go to.
* If you do not specify this value, the index list is empty, and any index
can be used.
* Separate multiple indexes with commas.
* The Splunk platform accepts and indexes events without a specified
index to a default index.
* No default.
s2s_indexes_validation = [ disabled | disabled_for_internal | enabled_for_all ]
* The method of index validation for Splunk-to-Splunk (S2S) events for this
token.
* A value of "disabled" means the Splunk platform doesn't validate the
event's index and the "indexes" setting has no effect for the S2S events.
* A value of "disabled_for_internal" means the Splunk platform doesn't
validate internal indexes and allows all S2S events destined for them. The
platform validates other indexes according to the "indexes" setting.
* A value of "enabled_for_all" means the platform validates all indexes
according to the "indexes" setting.
* The platform silently drops rejected events.
* Default: disabled
index = <string>
* The default index to use for this token.
* Default: the default index
sourcetype = <string>
* The default sourcetype to use if it is not specified in an event.
* Default: empty string
outputgroup = <string>
* The name of the forwarding output group to send data to.
* Default: empty string
queueSize = <integer>[KB|MB|GB]
* The maximum size of the in-memory input queue.
* Default: 500KB
persistentQueueSize = <integer>[KB|MB|GB|TB]
* Maximum size of the persistent queue file.
* Persistent queues can help prevent loss of transient data. For information on
persistent queues and how the 'queueSize' and 'persistentQueueSize' settings
interact, search the online documentation for "persistent queues"..
* If you set this to a value other than 0, then 'persistentQueueSize' must
be larger than either the in-memory queue size (as defined by the
'queueSize' setting in inputs.conf or 'maxSize' settings in [queue] stanzas
in server.conf).
* Default: 0 (no persistent queue)
connection_host = [ip|dns|proxied_ip|none]
* Specifies the host if an event doesn't have a host set.
* "ip" sets the host to the IP address of the system sending the data.
* "dns" sets the host to the reverse DNS entry for IP address of the system
that sends the data. For this to work correctly, set the forward DNS lookup
to match the reverse DNS lookup in your DNS configuration.
* "proxied_ip" checks whether an X-Forwarded-For header was sent
(presumably by a proxy server) and if so, sets the host to that value.
Otherwise, the IP address of the system sending the data is used.
* "none" leaves the host as specified in the HTTP header.
* No default.
useACK = <boolean>
* When set to "true", acknowledgment (ACK) is enabled. Events in a request
are tracked until they are indexed. An events status (indexed or not) can be
queried from the ACK endpoint with the ID for the request.
* When set to false, acknowledgment is not enabled.
* This setting can be set at the stanza level.
* Default: false
allowQueryStringAuth = <boolean>
* Enables or disables sending authorization tokens with a query string.
* This is a token level configuration. It may only be set for
a particular token.
* To use this feature, set to "true" and configure the client application to
include the token in the query string portion of the URL they use to send
data to HEC in the following format:
"https://<URL>?<your=query-string>&token=<your-token>" or
"https://<URL>?token=<your-token>" if the token is the first element in the
query string.
* If a token is sent in both the query string and an HTTP header, the token in
the query string takes precedence, even if this feature is disabled. In
other words, if a token is present in the query string, any token in the
header for that request is not used.
* NOTE: Query strings may be observed in transit and/or logged in cleartext.
There is no confidentiality protection for the transmitted tokens.
* Before using this in production, consult security personnel in your
organization to understand and plan to mitigate the risks.
* At a minimum, always use HTTPS when you enable this feature. Check your
client application, proxy, and logging configurations to confirm that
the token is not logged in clear text.
* Give minimal access permissions to the token in HEC and restrict the
use of the token only to trusted client applications.
* Default: false
WINDOWS INPUTS:
* Windows platform specific input processor.
# ***********
# Splunk software on Windows ships with several Windows-only inputs. They are
# defined in the default inputs.conf.
* Use the "disabled=" setting to enable/disable any of them.
* A short summary of the inputs follows:
* Perfmon: Monitors Windows performance counters, objects, and instances.
* WinRegMon: Tracks and report any changes that occur in the
local system Registry.
* ADMon: Indexes existing Active Directory (AD) objects and listens for AD
changes.
* WMI: Retrieves event logs remotely and locally through the Windows
Management Instrumentation subsystem. It can also gather performance
data remotely, as well as receive various system notifications. See
wmi.conf.spec for information on how to configure this input.
#*******
# The following Windows input specifications are for parsing on non-Windows
# platforms.
#*******
Performance Monitor
[perfmon://<name>]
* This section explains possible settings for configuring
the Windows Performance Monitor input.
* Each perfmon:// stanza represents an individually configured performance
monitoring input. If you configure the input through Splunk Web, then the
value of "<NAME>" matches what was specified there. While you can add
performance monitor inputs manually, it is a best practice to use Splunk
Web to configure them, because it is easy to mistype the values for
Performance Monitor objects, counters, and instances.
* NOTE: The perfmon stanza is for local systems ONLY. To define performance
monitor inputs for remote machines, use wmi.conf.
object = <string>
* A valid Performance Monitor object as defined within Performance
Monitor (for example, "Process," "Server," "PhysicalDisk").
* You can specify a single valid Performance Monitor object or use a
regular expression (regex) to specify multiple objects.
* This setting is required, and the input does not run if the setting is
not present.
* No default.
counters = <semicolon-separated list>
* This can be a single counter, or multiple valid Performance Monitor
counters.
* This setting is required, and the input does not run if the setting is
not present.
* "*" is equivalent to all available counters for a given Performance
Monitor object.
* No default.
nonmetric_counters = <semicolon-separated list>
* A list of performance counters on which the performance monitor input
must not perform sampling.
* When the input retrieves the value for a counter that is in this list,
it returns the latest value it retrieves, rather than an average of
the values that it got over the sampling interval, as defined by the
'samplingInterval' setting.
* Add counters to this setting in cases where the values that the input
returns for a setting would be incorrect if it were averaged over a
'samplingInterval', or where average, minimum, or maximum values for a
counter would not be of any interest.
* As an example, the "ID Process" counter works better as a non metric counter
because the most recent measurement of the counter is more relevant
than the average of any measurements of that counter.
* No default.
instances = <semicolon-separated list>
* One or more multiple valid Performance Monitor instances.
* "*" is equivalent to all available instances for a given Performance Monitor
counter.
* If applicable instances are available for a counter and this setting is not
present, then the input logs data for all available instances (this is the
same as setting "instances = *").
* If there are no applicable instances for a counter, then you can omit
this setting.
* No default.
interval = <integer>
* How often, in seconds, to poll for new data.
* This setting is required, and the input does not run if the setting is
not present.
* The recommended setting depends on the Performance Monitor object,
counter(s), and instance(s) that you define in the input, and how much
performance data you need.
* Objects with numerous instantaneous or per-second counters, such
as "Memory", "Processor", and "PhysicalDisk" should have shorter
interval times specified (anywhere from 1-3 seconds).
* Less volatile counters such as "Terminal Services", "Paging File",
and "Print Queue" can have longer intervals configured.
* Default: 300
mode = [single|multikv]
* Specifies how the performance monitor input generates events.
* Set to "single" to print each event individually.
* Set to "multikv" to print events in multikv (formatted multiple
key-value pair) format.
* Default: single
samplingInterval = <positive integer>
* How often, in milliseconds, to poll for new data.
* This is an advanced setting.
* Enables high-frequency performance sampling. The input collects
performance data every sampling interval. It then reports averaged data
and other statistics at every interval.
* The minimum legal value is 100, and the maximum legal value must be less
than the 'interval' setting.
* If not set, high-frequency sampling does not occur.
* No default (disabled).
stats = <average;count;dev;min;max>
* Reports statistics for high-frequency performance sampling.
* This is an advanced setting.
* Setting a 'samplingInterval' is required to use 'stats'.
* Acceptable values are: average, count, dev, min, max.
* You can specify multiple values by separating them with semicolons.
* Adds new fields that append the stats function name.
Setting 'average' replaces the stats displayed in the default field.
* No default. (disabled)
disabled = <boolean>
* Specifies whether or not the input is enabled.
* Set to 1 to disable the input, and 0 to enable it.
* Default: 0 (enabled)
showZeroValue = <boolean>
* Specifies whether or not the input collects zero-value event data.
* Set to 1 to capture zero value event data, and 0 to ignore such data.
* Default: 0 (ignore zero value event data)
useEnglishOnly = <boolean>
* Controls which Windows Performance Monitor API the input uses.
* If set to "true", the input uses PdhAddEnglishCounter() to add the
counter string. This ensures that counters display in English
regardless of the Windows machine locale.
* If set to "false", the input uses PdhAddCounter() to add the counter string.
* NOTE: if you set this setting to true, the 'object' setting does not
accept a regular expression as a value on machines that have a non-English
locale.
* Default: false
useWinApiProcStats = <boolean>
* Whether or not the Performance Monitor input uses process kernel mode and
user mode times to calculate CPU usage for a process, rather than using
the standard Performance Data Helper (PDH) APIs to calculate those values.
* A problem was found in the PDH APIs that causes Performance Monitor inputs
to show maximum values of 100% usage for a process on multicore Windows
machines, even when the process uses more than 1 core at a time.
* When you configure this setting to "true", the input uses the
GetProcessTime() function in the core Windows API to calculate
CPU usage for a process, for the following Performance Monitor
counters, only:
** Processor Time
** User Time
** Privileged Time
* This means that, if a process uses 5 of 8 cores on an 8-core machine, that
the input should return a value of around 500, rather than the incorrect 100.
* When you configure the setting to "false", the input uses the standard
PDH APIs to calculate CPU usage for a process. On multicore systems, the
maximum value that PDH APIs return is 100, regardless of the number of
cores in the machine that the process uses.
* Performance monitor inputs use the PDH APIs for all other Performance
Monitor counters. Configuring this setting has no effect on those counters.
* NOTE: If the Windows machine uses a non-English system locale, and you
have set 'useWinApiProcStats' to "true" for a Performance Monitor input,
then you must also set 'useEnglishOnly' to "true" for that input.
* Default: false
formatString = <string>
* Controls the print format for double-precision statistic counters.
* Do not use quotes when specifying this string.
* Default: %.20g
usePDHFmtNoCap100 = <boolean>
* Whether or not performance counter values that are greater than 100 (for example,
counter values that measure the processor load on computers with multiple
processors) are reset to 100.
* If set to "true", the counter values can exceed 100.
* If set to "false", the input resets counter values to 100 if the
processor load on multiprocessor computers exceeds 100.
* Default: false
Direct Access File Monitor
# For Windows systems only. # Does not use file handles [MonitorNoHandle://<path>] * This input intercepts file writes to the specific file. * <path> must be a fully qualified path name to a specific file. Wildcards and directories are not accepted. * This input type does not function on *nix machines. * You can specify more than one stanza of this type. disabled = <boolean> * Whether or not the input is enabled. * Default: 0 (enabled) index = <string> * Specifies the index where this input sends the data. * This setting is optional. * Default: the default index
Windows Event Log Monitor
[WinEventLog://<name>]
* This section explains possible settings for configuring the
Windows Event Log monitor.
* Each WinEventLog:// stanza represents an individually configured WinEventLog
monitoring input. If you you configure the input through Splunk Web, the
value of "<NAME>" matches what was specified there. While you can add
event log monitor inputs manually, it is best practice to use Splunk
Web to configure Windows event log monitor inputs because it is
easy to mistype the values for event log channels.
* NOTE: The WinEventLog stanza is for local systems ONLY. To define event log
monitor inputs for remote machines, use wmi.conf.
start_from = <string>
* How the input should chronologically read the Event Log channels.
* If you set this setting to "oldest", the input reads Windows event logs
from oldest to newest.
* If you set this setting to "newest" the input reads Windows event logs
in reverse, from newest to oldest. Once the input consumes the backlog of
events, it stops.
* If you set this setting to "newest", and at the same time set the
"current_only" setting to 0, the combination can result in the input
indexing duplicate events.
* Do not set this setting to "newest" and at the same time set the
"current_only" setting to 1. This results in the input not collecting
any events because you instructed it to read existing events from oldest
to newest and read only incoming events concurrently (A logically
impossible combination.)
* Default: "oldest"
use_old_eventlog_api = <boolean>
* Whether or not to read Event Log events with the Event Logging API.
* This is an advanced setting. Contact Splunk Support before you change it.
* A value of "true" means the input uses the Event Logging API (instead of the
Windows Event Log API) to read from the Event Log on Windows Server 2008,
Windows Vista, and later installations.
* Default: false (Use the API that is specific to the OS)
use_threads = <integer>
* Specifies the number of threads, in addition to the default writer thread,
that can be created to filter events with the deny list/allow list
regular expression.
* This is an advanced setting. Contact Splunk Support before you change it.
* The maximum number of threads is 15.
* Default: 0
thread_wait_time_msec = <integer>
* The interval, in milliseconds, between attempts to re-read Event Log files
when a read error occurs.
* This is an advanced setting. Contact Splunk Support before you change it.
* Default: 5000
#
# NOTE: The 'suppress_*' settings are similar to, but operate differently than,
# the 'evt_exclude_fields' setting. The 'suppress_*' settings avoid using the
# Windows API to gather Windows events that match the available
# fields, which helps with CPU performance. The 'evt_exclude_fields'
# is valid for all Windows Event Log fields, and while it does use
# the Windows API for all transactions, it discards the fields in
# each event that match, which helps reduce total data ingestion.
#
suppress_checkpoint = <boolean>
* Whether or not the Event Log strictly follows the 'checkpointInterval'
setting when it saves a checkpoint.
* This is an advanced setting. Contact Splunk Support before you change it.
* By default, the Event Log input saves a checkpoint from between zero
and 'checkpointInterval' seconds, depending on incoming event volume.
If you set this setting to "true", that does not happen.
* Default: false
suppress_sourcename = <boolean>
* Whether or not to exclude the 'sourcename' field from events.
* This is an advanced setting. Contact Splunk Support before you change it.
* When set to true, the input excludes the 'sourcename' field from events
and thruput performance (the number of events processed per second) improves.
* Default: false
suppress_keywords = <boolean>
* Whether or not to exclude the 'keywords' field from events.
* This is an advanced setting. Contact Splunk Support before you change it.
* When set to true, the input excludes the 'keywords' field from events and
thruput performance (the number of events processed per second) improves.
* Default: false
suppress_type = <boolean>
* Whether or not to exclude the 'type' field from events.
* This is an advanced setting. Contact Splunk Support before you change it.
* When set to true, the input excludes the 'type' field from events and
thruput performance (the number of events processed per second) improves.
* Default: false
suppress_task = <boolean>
* Whether or not to exclude the 'task' field from events.
* This is an advanced setting. Contact Splunk Support before you change it.
* When set to true, the input excludes the 'task' field from events and
thruput performance (the number of events processed per second) improves.
* Default: false
suppress_opcode = <boolean>
* Whether or not to exclude the 'opcode' field from events.
When set to true, the input excludes the 'opcode' field from events and
thruput performance (the number of events processed per second) improves.
* This is an advanced setting. Contact Splunk Support before you change it.
* Default: false
current_only = <boolean>
* Whether or not to acquire only events that arrive while the instance is
running.
* If you set this setting to 1, the input only acquires events that arrive
while the instance runs and the input is enabled. The input does not read
data which was stored in the Windows Event Log while the instance was not
running. This means that there will be gaps in the data if you restart the
instance or experiences downtime.
* If you set the setting to 0, the input first gets all existing events
already stored in the log that have higher event IDs (have arrived more
recently) than the most recent events acquired. The input then monitors
events that arrive in real time.
* If you set this setting to 0, and at the same time set the
'start_from' setting to "newest", the combination can result in the
indexing of duplicate events.
* Do not set this setting to 1 and at the same time set the
'start_from' setting to "newest". This results in the input not collecting
any events because you instructed it to read existing events from oldest
to newest and read only incoming events concurrently (A logically
impossible combination.)
* Default: 0 (false, gathering stored events first before monitoring
live events)
channel_wait_time = <integer>
* How long, in seconds, that the Windows Event Log input waits for an Event Log
channel that is not available to become available again.
* Some Event Log channels, like the Windows Defender channel, become
unavailable during a Windows Defender Platform update and it takes
some time to become available again.
* If the Event Log input is unable to collect event logs from a certain
Event Log channel, change this setting to an appropriate value.
For example, if the input does not collect Windows Defender event logs
after a Windows Defender Platform update, increase this value.
* The maximum wait time is 180 (3 minutes).
* Default: 0
batch_size = <integer>
* How many Windows Event Log items to read per request.
* If troubleshooting identifies that the Event Log input is a bottleneck in
acquiring data, increasing this value can help.
* NOTE: Splunk Support has seen cases where large values can result in a
stall in the Event Log subsystem. If you increase this value
significantly, monitor closely for trouble.
* In local and customer acceptance testing, a value of 10 was acceptable
for both throughput and reliability.
* Default: 10
checkpointInterval = <integer>
* How often, in seconds, that the Windows Event Log input saves a checkpoint.
* Checkpoints store the eventID of acquired events. This lets the input
continue monitoring at the correct event after a shutdown or outage.
* Default: 0
checkpointSync = <boolean>
* Determines whether the input processor forces writing a checkpoint file to disk
immediately or lets the operating system handle when writing of the
file to disk occurs.
* A value of "true" means the input processor triggers writing of a checkpoint
file to disk immediately. It also saves the file to a temporary location and
renames it instead of overwriting the existing file.
* Default: false
channel_wait_time = <integer>
* How long, in seconds, that the Windows Event Log input waits for an Event Log
channel that is not available to become available again.
* Some Event Log channels, like the Windows Defender channel, become
unavailable during a Windows Defender Platform update and it takes
some time to become available again.
* If the Event Log input is unable to collect event logs from a certain
Event Log channel, change this setting to an appropriate value.
For example, if the input does not collect Windows Defender event logs
after a Windows Defender Platform update, increase this value.
* The maximum wait time is 180 (3 minutes).
* Default: 0
disabled = <boolean>
* Whether or not the input is enabled.
* Set to 1 to disable the input, and 0 to enable it.
* Default: 0 (enabled)
evt_resolve_ad_obj = <boolean>
* How the input should interact with Active Directory while indexing Windows
Event Log events.
* If you set this setting to true, the input resolves the Active
Directory Security IDentifier (SID) objects to their canonical names for
a specific Windows Event Log channel.
* If you enable the setting, the rate at which the input reads events
on high-traffic Event Log channels can decrease. Latency can also increase
during event acquisition. This is due to the overhead involved in performing
AD translations.
* When you set this setting to true, you can optionally specify the domain
controller name or dns name of the domain to bind to with the 'evt_dc_name'
setting. The input connects to that domain controller to resolve the AD
objects.
* If you set this setting to false, the input does not attempt any resolution.
* Default: false (disabled) for all channels
evt_skip_GUID_resolution = <comma-separated list>
* A list of Windows Event Codes for which the Splunk platform does not contact
the domain controller to resolve global unique identifiers (GUIDs) that
are withing the event.
* Separate multiple event IDs or event ID ranges with commas.
* If the event code matches an event, The Splunk platform does not contact
the DC to resolve any GUIDs in this event.
* This setting only takes effect if 'evt_resolve_ad_obj' has a value of "true".
* If 'evt_resolve_ad_obj' has a value of "false", this setting has no effect.
* This setting has no effect on SID resolution.
* See 'Event ID list format' later in this file for the proper
formatting of the event list.
* Default: none
evt_dc_name = <string>
* Which Active Directory domain controller to bind to for AD object
resolution.
* If you prefix a dollar sign to a value (for example, $my_domain_controller),
the input interprets the value as an environment variable. If the
environment variable has not been defined on the host, it is the same
as if the value is blank.
* This setting is optional.
* This setting can be set to the NetBIOS name of the domain controller
or the fully-qualified DNS name of the domain controller. Either name
type can, optionally, be preceded by two backslash characters. The following
examples represent correctly formatted domain controller names:
* "FTW-DC-01"
* "\\FTW-DC-01"
* "FTW-DC-01.splunk.com"
* "\\FTW-DC-01.splunk.com"
* $my_domain_controller
evt_dns_name = <string>
* The fully-qualified DNS name of the domain that the input should bind to for
AD object resolution.
* This setting is optional.
evt_resolve_ad_ds = [auto|PDC]
* How the input should choose the domain controller to bind for
AD resolution.
* This setting is optional.
* If set to PDC, the input only contacts the primary domain controller
to resolve AD objects.
* If set to auto, the input lets Windows chose the best domain controller.
* If you set the 'evt_dc_name' setting, the input ignores this setting.
* Default: auto (let Windows determine the domain controller to use)
evt_ad_cache_disabled = <boolean>
* Enables or disables the AD object cache.
* Default: false (enabled)
evt_ad_cache_exp = <integer>
* The expiration time, in seconds, for AD object cache entries.
* This setting is optional.
* Default: 3600 (1 hour)
evt_ad_cache_exp_neg = <integer>
* The expiration time, in seconds, for negative AD object cache entries.
* This setting is optional.
* Default: 10
evt_ad_cache_max_entries = <integer>
* The maximum number of AD object cache entries.
* This setting is optional.
* Default: 1000
evt_exclude_fields = <comma-separated list>
* A list of valid Windows Event Log fields to exclude from Windows
Event Log events.
* Specify fields that you want excluded from each event report.
* Do not exclude fields that you have also added to allow lists or
deny lists. If fields are present in both, then 'evt_exclude_fields'
excludes those fields, regardless of their presence in the allow list
or deny list and the allow list or deny list will not behave as
expected. The input logs an error to splunkd.log in this case.
* This setting is similar to, but operates differently than, the
'suppress_*' settings. The 'suppress_*' settings avoid using the
Windows API to gather Windows events that match the available
fields, which helps with CPU performance. The 'evt_exclude_fields'
is valid for all Windows Event Log fields, and while it does use
the Windows API for all transactions, it discards the fields in
each event that match, which helps reduce total data ingestion.
* Does not effect event report if 'renderXML' is set to "true".
* The 'evt_exclude_fields' setting is valid for all Windows Event Log fields.
* No default.
evt_sid_cache_disabled = <boolean>
* Enables or disables account Security IDentifier (SID) cache.
* This setting is global. It affects all Windows Event Log stanzas.
* Default: 0
evt_sid_cache_exp = <unsigned integer>
* The expiration time, in seconds, for account SID cache entries.
* This setting is global. It affects all Windows Event Log stanzas.
* This setting is optional.
* Default: 3600
evt_sid_cache_exp_neg = <unsigned integer>
* The expiration time, in seconds, for negative account SID cache entries.
* This setting is optional.
* This setting is global. It affects all Windows Event Log stanzas.
* Default: 10
evt_sid_cache_max_entries = <unsigned integer>
* The maximum number of account SID cache entries.
* This setting is global. It affects all Windows Event Log stanzas.
* This setting is optional.
* Default: 10
index = <string>
* Specifies the index that this input should send the data to.
* This setting is optional.
* Default: The default index
Event Log filtering
# Filtering at the input layer is desirable to reduce the total
# processing load in network transfer and computation on the Splunk platform
# nodes that acquire and processing Event Log data.
whitelist = <comma-separated list> | key=regex [key=regex]
blacklist = <comma-separated list> | key=regex [key=regex]
whitelist1 = <comma-separated list> | key=regex [key=regex]
whitelist2 = <comma-separated list> | key=regex [key=regex]
whitelist3 = <comma-separated list> | key=regex [key=regex]
whitelist4 = <comma-separated list> | key=regex [key=regex]
whitelist5 = <comma-separated list> | key=regex [key=regex]
whitelist6 = <comma-separated list> | key=regex [key=regex]
whitelist7 = <comma-separated list> | key=regex [key=regex]
whitelist8 = <comma-separated list> | key=regex [key=regex]
whitelist9 = <comma-separated list> | key=regex [key=regex]
blacklist1 = <comma-separated list> | key=regex [key=regex]
blacklist2 = <comma-separated list> | key=regex [key=regex]
blacklist3 = <comma-separated list> | key=regex [key=regex]
blacklist4 = <comma-separated list> | key=regex [key=regex]
blacklist5 = <comma-separated list> | key=regex [key=regex]
blacklist6 = <comma-separated list> | key=regex [key=regex]
blacklist7 = <comma-separated list> | key=regex [key=regex]
blacklist8 = <comma-separated list> | key=regex [key=regex]
blacklist9 = <comma-separated list> | key=regex [key=regex]
* These settings are optional.
* Both numbered and unnumbered allow lists and deny lists support two formats:
* A comma-separated list of event IDs.
* A list of key=regular expression pairs.
* You cannot combine these formats. You can use either format on a specific
line.
* Numbered allow list settings are permitted from 1 to 9, so whitelist1 through
whitelist9 and blacklist1 through blacklist9 are supported.
* If no allow list or deny list rules are present, the input reads all events.
Event Log allow list and deny list formats
* Event ID list format:
* A comma-separated list of terms.
* Terms may be a single event ID (e.g. 6) or range of event IDs (e.g. 100-200)
* Example: 4,5,7,100-200
* This applies to events with IDs 4, 5, 7, or any event ID between 100
and 200, inclusive.
* A single asterisk (*) means all event codes.
* The event ID list format provides no additional functionality over the
key=regex format, but can be easier to understand:
List format: 4,5,7,100-200
Regex equivalent: EventCode=%^(4|5|7|1..|200)$%
* key=regex format:
* A whitespace-separated list of Event Log components to match, and
regular expressions to match against against them.
* There can be one match expression or multiple expressions per line.
* The key must belong to the set of valid keys provided in the "Valid
keys for the key=regex format" section.
* The regex consists of a leading delimiter, the regex expression, and a
trailing delimiter. Examples: %regex%, *regex*, "regex"
* When multiple match expressions are present, they are treated as a
logical AND. In other words, all expressions must match for the line to
apply to the event.
* If the value represented by the key does not exist, it is not considered
a match, regardless of the regex.
* Example:
whitelist = EventCode=%^200$% User=%jrodman%
Include events only if they have EventCode 200 and relate to User jrodman
# Valid keys for the key=regex format:
* The following keys are equivalent to the fields that appear in the text of
the acquired events:
* Category, CategoryString, ComputerName, EventCode, EventType, Keywords,
LogName, Message, OpCode, RecordNumber, Sid, SidType, SourceName,
TaskCategory, Type, User
* There are two special keys that do not appear literally in the event.
* $TimeGenerated: The time that the computer generated the event
* $Timestamp: The time that the event was received and recorded by the
Event Log service.
* The 'EventType' key is only available on Windows Server 2003 /
Windows XP and earlier.
* The 'Type' key is only available on Windows Server 2008 /
Windows Vista and later.
* For a detailed definition of these keys, see the
"Monitor Windows Event Log Data" topic in the online documentation.
suppress_text = <boolean>
* Whether or not to include the description of the event text for a
given Event Log event.
* This setting is optional.
* Set this setting to true to suppress the inclusion of the event
text description.
* Set this value to false to include the event text description.
* Default: false
renderXml = <boolean>
* Whether or not the input returns the event data in XML (eXtensible Markup
Language) format or in plain text.
* Set this to "true" to render events in XML.
* Set this to "false" to output events in plain text.
* If you set this setting to "true", you should also set the 'suppress_text',
'suppress_sourcename', 'suppress_keywords', 'suppress_task', and
'suppress_opcode' settings to "true" to improve thruput performance.
* Default: false
Active Directory Monitor
[admon://<name>] * This section explains possible settings for configuring the Active Directory monitor input. * Each admon:// stanza represents an individually configured Active Directory monitoring input. If you configure the input with Splunk Web, then the value of "<NAME>" matches what was specified there. While you can add Active Directory monitor inputs manually, it is best practice to use Splunk Web to configure Active Directory monitor inputs because it is easy to mistype the values for Active Directory monitor objects. targetDc = <string> * The fully qualified domain name of a valid, network-accessible Active Directory domain controller (DC). * This setting is case sensitive. Do not use 'targetdc' or 'targetDC', but rather 'targetDc'. * Default: The DC that the local host used to connect to AD. The input binds to its root Distinguished Name (DN). startingNode = <string> * Where in the Active Directory directory tree to start monitoring. * The user that you configure Splunk software to run as at installation determines where the input starts monitoring. * Default: the root of the directory tree monitorSubtree = <boolean> * Whether or not to monitor the subtree(s) of a given Active Directory tree path. * Set this to 1 to monitor subtrees of a given directory tree path and 0 to monitor only the path itself. * Default: 1 (monitor subtrees of a given directory tree path) disabled = <boolean> * Whether or not the input is enabled. * Set this to 1 to disable the input and 0 to enable it. * Default: 0 (enabled) index = <string> * The index to store incoming data into for this input. * This setting is optional. * Default: the default index printSchema = <boolean> * Whether or not to print the Active Directory schema. * Set this to 1 to print the schema and 0 to not print the schema. * Default: 1 (print the Active Directory schema) baseline = <boolean> * Whether or not to query baseline objects. * Baseline objects are objects which currently reside in Active Directory. * Baseline objects also include previously deleted objects. * Set this to 1 to query baseline objects, and 0 to not query baseline objects. * Default: 0 (do not query baseline objects)
Windows Registry Monitor
[WinRegMon://<name>]
* This section explains possible settings for configuring the Windows Registry
Monitor input.
* Each WinRegMon:// stanza represents an individually configured
WinRegMon monitoring input.
* If you configure the inputs with Splunk Web, the value of "<NAME>" matches
what was specified there. While you can add event log monitor inputs
manually, it is best practice to use Splunk Web to configure
Windows registry monitor inputs because it is easy to mistype the values
for Registry hives and keys.
* The WinRegMon input is for local systems only. You cannot monitor the
Registry remotely.
proc = <string>
* The processes this input should monitor for Registry access.
* If set, matches against the process name which performed the Registry
access.
* The input includes events from processes that match the regular expression
that you specify here.
* The input filters out events for processes that do not match the
regular expression.
* Default: .* (match all processes)
hive = <string>
* The Registry hive(s) that this input should monitor for Registry access.
* If set, matches against the Registry key that was accessed.
* The input includes events from Registry hives that match the
regular expression that you specify here.
* The input filters out events for Registry hives that do not match the
regular expression.
* No default.
type = <string>
* A regular expression that specifies the type(s) of Registry event(s)
that you want the input to monitor.
* No default.
baseline = <boolean>
* Whether or not the input should get a baseline of Registry events
when it starts.
* If you set this to 1, the input captures a baseline for
the specified hive when it starts for the first time. It then
monitors live events.
* Default: 0 (do not capture a baseline for the specified hive
first before monitoring live events)
baseline_interval = <integer>
* Selects how much downtime in continuous registry monitoring should trigger
a new baseline for the monitored hive and/or key.
* In detail:
* Sets the minimum time interval, in seconds, between baselines.
* At startup, a WinRegMon input does not generate a baseline if less time
has passed since the last checkpoint than baseline_interval chooses.
* In normal operation, checkpoints are updated frequently as data is
acquired, so this will cause baselines to occur only when monitoring was
not operating for a period of time.
* If baseline is set to 0 (disabled), the setting has no effect.
* Default: 86400 (1 day)
disabled = <boolean>
* Whether or not the input is enabled.
* Set this to 1 to disable the input, or 0 to enable it.
* Default: 0 (enabled)
index = <string>
* The index that this input should send the data to.
* This setting is optional.
* Default: the default index
Windows Host Monitoring
[WinHostMon://<name>]
* This section explains possible settings for configuring the Windows host
monitor input.
* Gathers status information from the local Windows system components as
per the 'type' field, described after this section.
* Each WinHostMon:// stanza represents an WinHostMon monitoring input.
* The "<name>" component of the stanza name is used as the source field
on generated events, unless an explicit source setting is added to the
stanza. It does not affect what data is collected (see type setting for
that).
* If you configure the input in Splunk Web, the value of "<name>" matches
what was specified there.
* NOTE: The WinHostMon input is for local Windows systems only. You
cannot monitor Windows host information remotely.
type = <semicolon-separated list>
* An expression that specifies the type(s) of host inputs
that you want the input to monitor.
* Type can be (case insensitive):
Computer;Process;Processor;NetworkAdapter;Service;OperatingSystem;Disk;Driver;Roles
* No default.
interval = <integer>
* The interval, in seconds, between when the input runs to gather
Windows host information and generate events.
* See 'interval' in the Scripted input section for more information.
disabled = <boolean>
* Whether or not the input is enabled.
* Set this to 1 to disable the input, or 0 to enable it.
* Default: 0 (enabled)
index = <string>
* The index that this input should send the data to.
* This setting is optional.
* Default: the default index
[WinPrintMon://<name>]
* This section explains possible settings for configuring the Windows print
monitor input.
* Each WinPrintMon:// stanza represents an WinPrintMon monitoring input.
The value of "<name>" matches what was specified in Splunk Web.
* NOTE: The WinPrintMon input is for local Windows systems only.
* The "<name>" component of the stanza name is used as the source field
on generated events, unless an explicit source setting is added to the
stanza. It does not affect what data is collected (see type setting for
that).
type = <semicolon-separated list>
* An expression that specifies the type(s) of print inputs
that you want the input to monitor.
* Type can be (case insensitive):
Printer;Job;Driver;Port
* No default.
interval = <integer>
* The interval, in seconds, between when the input runs to gather
Windows host information and generate events.
* See 'interval' in the Scripted input section for more information.
baseline = <boolean>
* Whether or not to capture a baseline of print objects when the
input starts for the first time.
* If you set this setting to 1, the input captures a baseline of
the current print objects when the input starts for the first time.
* Default: 0 (do not capture a baseline)
disabled = <boolean>
* Whether or not the input is enabled.
* Set to 1 to disable the input, or 0 to enable it.
* Default: 0 (enabled)
index = <string>
* The index that this input should send the data to.
* This setting is optional.
* Default: the default index
[WinNetMon://<name>]
* This section explains possible settings for configuring
a Network Monitor input.
* Each WinNetMon:// stanza represents an individually configured network
monitoring input. The value of "<name>" matches what was specified
in Splunk Web. It is best practice to use Splunk Web to
configure Network Monitor inputs because it is easy to mistype
the values for Network Monitor objects.
remoteAddress = <regular expression>
* A regular expression that represents the remote IP address of a
