SPLK-1002 Advanced Searching and Statistics Practice Question
You need to find the percentage of total events contributed by each sourcetype. Which command should follow index=* | stats count by sourcetype?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
eventstats sum(count) as total | eval percent = count/total*100
`eventstats sum(count) as total` adds a new field 'total' containing the sum of the count field across all events, and then `eval percent = count/total*100` computes the percentage for each sourcetype. Option A (`addtotals`) adds row totals, not a column total, so it cannot be used to compute percentages of total. Option C uses `sum(count)` inside `eval`, which is a statistical function not available in `eval`. Option D (`appendpipe`) appends a row with the total, not a column, making the calculation incorrect because the total is not available per event in the subsequent `eval`.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
addtotals
Why it's wrong here
addtotals adds row totals, not column totals.
- ✓
eventstats sum(count) as total | eval percent = count/total*100
Why this is correct
eventstats adds total column, then eval computes percentage per row.
- ✗
eval percent = count / sum(count) * 100
Why it's wrong here
sum(count) is an aggregation and cannot be used in eval without a prior stats.
- ✗
appendpipe [stats sum(count) as total] | eval percent = count/total*100
Why it's wrong here
appendpipe adds a new row with the total, not a column, so the eval will divide count by total only for that row.
