workload_rules.conf

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

workload_rules.conf.spec

   Version 8.1.1

OVERVIEW

 This file contains descriptions of the settings that you can use to
 configure workloads classification rules for splunk.

 There is a workload_rules.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 workload_rules.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 workload_rules.conf.example. You do not need to restart the Splunk instance
 to enable workload_rules.conf 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 takes precedence.
   * If a setting is defined at both the global level and in a specific
     stanza, the value in the specific stanza takes precedence.

 CAUTION: Do not alter the settings in the workload_rules.conf file unless you know
     what you are doing.  Improperly configured workload rules might result in
     splunkd crashes, memory overuse, or both.

[workload_rule:<rule_name>]

predicate = <string>
* Specifies the predicate of this workload classification rule.
* The format is logical expression with predicate as <type>=<value>.
* For example, "app=search AND (NOT role=power)".
* The valid <type> are "app", "role", "user", "index",
  "search_type", "search_mode" and "search_time_range". 
  The <value> is the exact value of the <type>.
* For "app" type, the value is the name of the app. For example, "app=search".
* For "role" type, the value is the name of the role. For example, "role=admin".
* For "index" type, the value is the name of the index. For example,
  "index=_internal". Note that the value can refer to an internal or public index.
* For "user" type, the value is the name of any valid user. For example,
  "user=bob". Note that the reserved internal user "noboby" is invalid; the
  reserved internal user "splunk-system-user" is valid.
* For "search_type" type, the value is the type of the search. Valid search 
  types include "adhoc", "scheduled", "datamodel_acceleration", 
  "report_acceleration" and "summary_index".
* For "search_mode" type, the value is the mode of the search. Valid modes 
  include "realtime" and "historical".
* For "search_time_range" type, the value is the time range of the search. 
  For now, value can only be "alltime".
* For "runtime" type, the value is the amount of time a search must run in a 
  workload pool to trigger a specified action, such as alert, move or abort.
  Valid units for runtime values include s, second, seconds, m, minute, minutes,
  and h, hour, hours.
* Required.

workload_pool = <string>
* Specifies the name of the workload pool, for example "pool1".
* The pool name that you specify must already be defined in the
  [workload_pool:<pool_name>] stanza in workload_pools.conf.

action = alert | move | abort
* Specifies the action to take when a search exceeds the specified runtime value.
* The action "alert" sends a notification message to Splunk Web that indicates
  the runtime of the search.
* The action "move" moves the search from the original workload pool to a
  designated alternate workload pool, and sends a notification message to
  Splunk Web.
* The action "abort" kills the search, and sends a notification message to
  Splunk Web.
* Optional.

schedule = always_on | time_range | every_day | every_week | every_month
* Specifies whether the rule is always on or has a valid time range that
  expires.
* Optional. If it's empty, it means the rule is always on.

start_time = <string>
* When 'schedule' is set to "time_range", 'start_time' specifies the exact time
  that the valid time range starts, including date, time and time zone.
* When 'schedule' is set to "every_week" or "every_month", it specifies
  the start hour.
* Optional.

end_time = <string>
* When 'schedule' is set to "time_range", 'end_time' specifies the exact time
  that the valid time range ends, including date, time and time zone.
* When 'schedule' is set to "every_week" or "every_month", it specifies the end
  hour.
* Optional.

every_week_days = <string>
* Specifies recurring days of the week.
* Supports numbers from 0 to 6, where 0 represents Sunday.
* Only applies when 'schedule' is set to "every_week".
* Optional.

every_month_days = <string>
* Specifies recurring days of the month.
* Supports numbers from 1 to 31, where 1 represents the 1st day of the month.
* Only applies when 'schedule' is set to "every_month".
* Optional.

user_message = <string>
* Specifies the message shown in the search job inspector if the rule is
  applied to a search.
* Cannot exceed 140 characters.
* Optional.

[workload_rules_order]

rules = <string>
* List of all workload classification rules.
* The format of the "string" is comma separated items, "rule1,rule2,...".
* The rules listed are defined in [workload_rule:<rule_name>] stanza.
* The order of the rule name in the list determines the priorities of that rule.
  For example, in "rule1,rule2", rule1 has higher priority than rule2.
* The default value for this property is empty, meaning there is no rule defined.

[search_filter_rule:<rule_name>]

predicate = <string>
* Specifies the predicate of this workload classification rule.
* The format is logical expression with predicate as <type>=<value>.
* For example, "app=search AND (NOT role=power)".
* The valid <type> are "app", "role", "user", "index",
  "search_type", "search_mode" and "search_time_range". 
  The <value> is the exact value of the <type>.
* For "app" type, the value is the name of the app. For example, "app=search".
* For "role" type, the value is the name of the role. For example, "role=admin".
* For "index" type, the value is the name of the index. For example,
  "index=_internal". Note that the value can refer to an internal or public index.
* For "user" type, the value is the name of any valid user. For example,
  "user=bob". Note that the reserved internal user "noboby" is invalid; the
  reserved internal user "splunk-system-user" is valid.
* For "search_type" type, the value is the type of the search. Valid search 
  types include "adhoc", "scheduled", "datamodel_acceleration", 
  "report_acceleration" and "summary_index".
* For "search_mode" type, the value is the mode of the search. Valid modes 
  include "realtime" and "historical".
* For "search_time_range" type, the value is the time range of the search. 
  For now, value can only be "alltime".
* Required.

action = filter
* Specifies the action to take when a search meets the rule criteria.
* The action "filter" is defined for search filter rules. If a search meets the rule
  criteria, the search is not executed.
* Required.

schedule = always_on | time_range | every_day | every_week | every_month
* Specifies whether the rule is always on or has a valid time range that
  expires.
* Optional. If it's empty, it means the rule is always on.

start_time = <string>
* When 'schedule' is set to "time_range", 'start_time' specifies the exact time
  that the valid time range starts, including date, time and time zone.
