As a Splunk administrator, you're responsible for managing and optimizing aspects of your Splunk deployment. You are interested in how the Splunk platform handles event segmentation, and you are looking to optimize or improve event segmentation within your deployment. Your aim is to make searches faster and use less disk space.

The Splunk platform uses tsidx (time series index) files to make data in your event indexes quicker to search. A tsidx file associates each unique keyword in your data with location references to events. You want to return a list of all of the terms or indexed fields from the tsidx files that comprise your event indexes.

Solution

You can use the walklex command to return a list of terms or indexed fields from your event indexes. The walklex command works on event indexes, as well as warm and cold buckets.
