Splunk Exam SPLK-1004 Topic 10 Question 37 Discussion

The correct command to generate a summary index containing a count of events by product_id is:

sistats count by product_id

Here's why this works:

sistats : This command is specifically designed for creating summary indexes. It pre-aggregates data and stores it in a format optimized for fast retrieval.

count by product_id : This part of the command calculates the count of events grouped by the product_id field.

Summary indexing is useful when you want to store pre-aggregated data for faster reporting. For example, instead of querying raw data every time, you can query the summary index to get quick results.

Other options explained:

Option A : Incorrect because stats si(product_id) is invalid syntax.

Option B : Incorrect because stats is used for real-time aggregation but does not create summary indexes.

Option D : Incorrect because sistats summary index by product_id is invalid syntax.

Example:

index=main | sistats count by product_id
