Which of the following is true about thesummariesonly=targument of thetstatscommand?

Comprehensive and Detailed Step by Step Explanation:

Thesummariesonly=targument of thetstatscommandapplies only to accelerated data models. It ensures that the search uses only the precomputed summaries of the data model, ignoring raw data.

Here’s why this works:

Purpose of summariesonly=t: When set totrue, thetstatscommand restricts the search to use only the accelerated summaries of the data model. This improves performance but may exclude events that are not part of the summary.

Accelerated Data Models: Acceleration creates summaries of data models, making them faster to query. Usingsummariesonly=tensures that only these summaries are queried, avoiding raw data entirely.

Other options explained:

Option B: Incorrect becausesummariesonly=tdoes not apply to unaccelerated data models; it requires acceleration to function.

Option C: Incorrect becausesummariesonly=tapplies only to accelerated data models, not unaccelerated ones.

Option D: Incorrect becausesummariesonly=ttypically produces fewer results, as it excludes raw data that is not part of the summary.

Example:

| tstats count WHERE index=_internal summariesonly=t BY sourcetype

This query uses only the accelerated summaries of the_internalindex.
