The tscollect command uses indexed fields to create time series index (tsidx) files in a namespace that you define. The result tables in these files are a subset of the data that you've already indexed. This then enables you to use the tstats command to search and report on these tsidx files instead of searching raw data. Because you are searching on a subset of the full index, the search should complete faster than it would otherwise.

The tscollect command can create multiple tsidx files in the same namespace. The command begins a new tsidx file when it determines that the tsidx file it is currently creating has gotten big enough.

Only users with the indexes_edit capability can run this command. See Usage.

If you are upgrading from Splunk Enterprise 5.x and you used the experimental version of the tscollect command in that release, the format of the tsidx files in Splunk Enterprise 6.x is not compatible with the earlier version.


... | tscollect [namespace=<string>] [squashcase=<bool>] [keepresults=<bool>]

Optional arguments

Syntax: keepresults = true | false
Description: If true, tscollect outputs the same results it received as input. If false, tscollect returns the count of results processed (this is more efficient since it does not need to store as many results).
Default: false
Syntax: namespace=<string>
Description: Define a location for the tsidx file(s). If namespace is provided, the tsidx files are written to a directory of that name under the main tsidxstats directory (that is, within $SPLUNK_DB/tsidxstats). These namespaces can be written to multiple times to add new data.
Default: If namespace is not provided, the files are written to a directory within the job directory of that search, and will live as long as the job does. If you have Splunk Enterprise, you can configure the namespace location by editing indexes.conf and setting the attribute tsidxStatsHomePath.
Syntax: squashcase = true | false
Description: Specify whether or not the case for the entire field::value tokens are case sensitive when it is put into the lexicon. To create indexed field tsidx files that are similar to those created by Splunk Enterprise, set squashcase=true for results to be converted to all lowercase.
Default: false


You must have the indexes_edit capability to run the tscollect command. By default, the admin role has this capability. The user and power roles do not have this capability.


Example 1: Write the results table to tsidx files in namespace foo.

... | tscollect namespace=foo

Example 2: Retrieve events from the main index and write the values of field foo to tsidx files in the job directory.

index=main | fields foo | tscollect

I expected to see something about tsdix stats cleanup here in manuals, but am not finding it. There are some entries in answers but it seems like version specific info should be here.

@Yoho: Tsidx created using tscollect on Splunk 6 *still* lives on the search head. Only tsidx created by data model acceleration lives distributed on the indexers.

Don't know if it's still the case with Splunk 6.X but tsidxfiles created by this command were created on the search head and *not* the indexer with previous version. I think it's worth mentioning.
