It changes the output to the “prestats” format, which is used to pass the results into aggregation functions such as chart, stats, or timechart. prestats – If you’re going to use append, this option is required to be set to true.append – This option allows you to chain tstats searches together into a unified search result, similar to the union or append commands.In this context, summaries are synonymous with accelerated data. summariesonly – As the name implies, this option tells Splunk whether to search summaries or summaries plus raw data.This option is only applicable to accelerated data model searches. allow_old_summaries – Allows Splunk to use results that were generated prior to a change of the data model.Commonly utilized arguments (set to either true or false) are: Like most Splunk commands, there are arguments you can pass to it (see the docs page for a full list). Then, open the Job Inspector to find the tstats command used in the background for your pivot under “Normalized Search.” If you’re ever confused as to how to turn your data model search into a tstats version, one trick is to recreate the equivalent of your search in the Datasets (Pivot) function. Tstats search: | tstats dc(All_st_ip) AS dest_ip from datamodel=Network_Traffic by All_Traffic.src_ip | stats dc(All_st_ip) by All_Traffic.src_ip Standard datamodel search: | datamodel Network_Traffic All_Traffic search Tstats search: | tstats count where index=os sourcetype=syslog earliest=-5m by splunk_serverĮxample 3: CIM Data Model Search – Count of Destination IPs by Source IP Tstats search: | tstats count where index=* OR index=_* by index, sourcetypeĮxample 2: Indexer Data Distribution over 5 Minutes Syntax (Simplified) | tstats (field) AS renamed-field where by field The following fields are indexed by default and can be searched with tstats:Īdditional metadata fields that can be used but aren’t part of the tsidx are: You’ll want to make sure you specify a WHERE clause with an index to keep the scope of your search as specific as possible. If you’re used to SQL, you can think of it like replacing SELECT with “| tstats” and swapping the order of your WHERE and GROUP BY clauses. The syntax for tstats takes some practice to get right. The tstats command is most commonly employed for accelerated data models and calculating metrics for your event data. This limits the flexibility somewhat, but evals can usually be implemented in another way as a workaround.
