You can apply different log levels to different sets of channels. Log level expression options level Syntax: log_ Description: Valid values are the Splunk platform internal logging levels: debug, info, warn, and error, and fatal. Search_arch_sort_normalizationįor more information about specific search optimization types, see Built-in optimizations. This optimization type is disabled by default. Replace stats command with tstats command optimization Search_optimization.replace_stats_cmds_with_tstats Replace append command with union command optimization Search_optimization.replace_append_with_union Search_optimization.required_field_values Search_optimization.projection_elimination You might use this setting to make an ad hoc search job stay in the system for 24 hours or 7 days. The default lifetime of an ad hoc search is 10 minutes. The search job lifetime is the amount of time that the job exists in the system before it is deleted. Default: true set_ttl Syntax: set_ttl = Description: Specifies the lifetime of the search job using time modifiers like 1d for one day or 12h for twelve hours. Default: 1 search_optimization Syntax: search_optimization = Description: Enables or disables all optimizations for the search. The difference is that it enables you to apply event sampling to a subsearch, while the Splunk Web version of event sampling is applied only to the main search. The sample_ratio does the same thing as the event sampling feature that you can manage through Splunk Web. The sample_ratio argument requires that search be the generating command of the search to which you are applying noop.

For example, if you supply | noop sample_ratio=25, the Splunk software returns a random sample of 1 out of every 25 events from the search result set. Default: true sample_ratio Syntax: sample_ratio = Description: Sets a randomly-sampled subset of results to return from a given search. To disable multiple optimization types, create a comma-separated list of search_optimization. = Description: Enables or disables a specific type of search optimization for the search. optimization_type Syntax: search_optimization. The log channel list must be double-quoted and semicolon-separated.
" Description: Sets or changes the log levels for one or more log channels at search startup. The list of attribute value changes must be enclosed in quotes. They are not reused after the search finishes. These value changes apply to the search job for the lifetime of the job. " Description Identifies an appender from log-searchprocess.log and specifies changed values for one or more attributes that belong to that appender. Optional arguments appender-expression Syntax: log_appender = ". If you are looking for a way to add comments to your search, see Add comments to searches in the Search Manual. You cannot use the noop command to add comments to a search. It includes several arguments that you can use to troubleshoot search optimization issues. The noop command is an internal command that you can use to debug your search. The noop command is an internal, unsupported, experimental command.
