SPLK-1002 Advanced Searching and Statistics Practice Question

A user wants to calculate the average response time per user, but only for users who have more than 10 events. Which search approach is efficient?

⚠ Common exam trap

Candidates often confuse `eventstats` with `stats` and think they can filter on an aggregated field like `count` without first computing it in the same `stats` command, leading them to choose Option A or D.

Correct answer & explanation

index=web | stats avg(response_time) as avg, count as cnt by user | where cnt>10

It first uses `stats` to compute both the average response time and the event count per user, then filters with `where cnt>10` to keep only users who have more than 10 events. This ensures the average is calculated only after grouping, and the count condition is applied on the aggregated result, which is efficient and accurate.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • index=web | eventstats avg(response_time) as avg by user | where count>10

    Why it's wrong here

    eventstats does not compute count; 'count' is undefined.

  • index=web | stats avg(response_time) as avg, count as cnt by user | where cnt>10

    Why this is correct

    Computes both statistics and filters correctly.

  • index=web | where count>10 | stats avg(response_time) by user

    Why it's wrong here

    The field 'count' does not exist at the time of the where clause.

  • index=web | stats avg(response_time) as avg by user | where count>10

    Why it's wrong here

    The field 'count' is not computed in this search.
