SPLK-1002 Advanced Searching and Statistics Practice Question
An analyst needs to calculate the average response time for each web server, but only for requests that returned status code 200. The field 'response_time' is numeric. Which search correctly achieves this?
⚠ Common exam trap
It's easy for candidates to confuse `eventstats` with `stats`, thinking `eventstats` can produce a summary table, or they incorrectly use `eval` with aggregation functions, not realizing that `eval` operates on individual events and cannot perform group-by calculations.

Correct answer & explanation
✓
index=web status=200 | stats avg(response_time) by server
It first filters the data to only include events with status=200 using a search-time field filter, then uses the `stats` command with `avg(response_time) by server` to compute the average response time per server. This ensures that only successful requests are included in the aggregation, and the `by server` clause correctly groups the results by each web server.
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 | transaction server maxspan=1m | stats avg(response_time) by server
Why it's wrong here
Transaction is for grouping related events; not appropriate for simple aggregation.
- ✗
index=web status=200 | eventstats avg(response_time) as avg_time by server
Why it's wrong here
eventstats adds a field to each event but does not produce a summary table; it retains all events.
- ✗
index=web | eval avg_time = avg(response_time) by server | search status=200
Why it's wrong here
eval cannot compute aggregate functions; also search after eval is inefficient.
- ✓
index=web status=200 | stats avg(response_time) by server
Why this is correct
Correct: filter first, then aggregate.
