alert_actions.conf

The following are the spec and example files for alert_actions.conf.

alert_actions.conf.spec

#   Version 7.2.5
#
# This file contains possible attributes and values for configuring global
# saved search actions in alert_actions.conf.  Saved searches are configured
# in savedsearches.conf.
#
# There is an alert_actions.conf in $SPLUNK_HOME/etc/system/default/.
# To set custom configurations, place an alert_actions.conf in
# $SPLUNK_HOME/etc/system/local/.  For examples, see
# alert_actions.conf.example. You must restart Splunk to enable
# configurations.
#
# To learn more about configuration files (including precedence) please 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, attributes are combined. In the case of
#    multiple definitions of the same attribute, the last definition in the
#    file wins.
#  * If an attribute is defined at both the global level and in a specific
#    stanza, the value in the specific stanza takes precedence.

maxresults = <integer>
* Set the global maximum number of search results sent via alerts.
* Defaults to 100.

hostname = [protocol]<host>[:<port>]
* Sets the hostname used in the web link (url) sent in alerts.
* This value accepts two forms.
  * hostname
       examples: splunkserver, splunkserver.example.com
  * protocol://hostname:port
       examples: http://splunkserver:8000, https://splunkserver.example.com:443
* When this value is a simple hostname, the protocol and port which
  are configured within splunk are used to construct the base of
  the url.
* When this value begins with 'http://', it is used verbatim.
  NOTE: This means the correct port must be specified if it is not
  the default port for http or https.
* This is useful in cases when the Splunk server is not aware of
  how to construct an externally referenceable url, such as SSO
  environments, other proxies, or when the Splunk server hostname
  is not generally resolvable.
* Defaults to current hostname provided by the operating system,
  or if that fails, "localhost".
* When set to empty, default behavior is used.

ttl     = <integer>[p]
* Optional argument specifying the minimum time to live (in seconds)
  of the search artifacts, if this action is triggered.
* If p follows integer, then integer is the number of scheduled periods.
* If no actions are triggered, the artifacts will have their ttl determined
  by the "dispatch.ttl" attribute in savedsearches.conf.
* Defaults to 10p
* Defaults to 86400 (24 hours)   for: email, rss
* Defaults to   600 (10 minutes) for: script
* Defaults to   120 (2 minutes)  for: summary_index, populate_lookup

maxtime = <integer>[m|s|h|d]
* The maximum amount of time that the execution of an action is allowed to
  take before the action is aborted.
* Use the d, h, m and s suffixes to define the period of time:
  d = day, h = hour, m = minute and s = second.
  For example: 5d means 5 days.
* Defaults to 5m for everything except rss.
* Defaults to 1m for rss.

track_alert = [1|0]
* Indicates whether the execution of this action signifies a trackable alert.
* Defaults to 0 (false).

command = <string>
* The search command (or pipeline) which is responsible for executing
  the action.
* Generally the command is a template search pipeline which is realized
  with values from the saved search - to reference saved search
  field values wrap them in dollar signs ($).
* For example, to reference the savedsearch name use $name$. To
  reference the search, use $search$

is_custom = [1|0]
* Specifies whether the alert action is based on the custom alert
  actions framework and is supposed to be listed in the search UI.

payload_format = [xml|json]
* Configure the format the alert script receives the configuration via
  STDIN.
* Defaults to "xml"

label = <string>
* For custom alert actions: Define the label shown in the UI. If not
  specified, the stanza name will be used instead.

description = <string>
* For custom alert actions: Define the description shown in the UI.

icon_path = <string>
* For custom alert actions: Define the icon shown in the UI for the alert
  action. The path refers to appserver/static within the app where the
  alert action is defined in.

forceCsvResults = auto|<bool>
* If set to a true boolean, any saved search that includes this action will
  always store results in CSV format, instead of the internal SRS format.
* If set to a false boolean, results will always be serialized using the
  internal SRS format.
* If set to "auto", results will be serialized as CSV if the 'command' setting
  in this stanza starts with "sendalert" or contains the string
  "$results.file$".
* Defaults to "auto".

alert.execute.cmd = <string>
* For custom alert actions: Explicitly specify the command to be executed
  when the alert action is triggered. This refers to a binary or script
  in the bin folder of the app the alert action is defined in, or to a
  path pointer file, also located in the bin folder.
* If a path pointer file (*.path) is specified, the contents of the file
  is read and the result is used as the command to be executed.
  Environment variables in the path pointer file are substituted.
* If a python (*.py) script is specified it will be prefixed with the
  bundled python interpreter.

alert.execute.cmd.arg.<n> = <string>
* Provide additional arguments to the alert action execution command.
  Environment variables are substituted.
