SPLK-1002 Advanced Visualization and Lookups Practice Question
An analyst creates a timechart to display the average CPU usage over time for multiple hosts. The chart shows a single line representing the overall average instead of separate lines per host. What is the most likely cause?
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
✓
The search uses 'timechart span=1h avg(cpu)' without splitting.
The search uses 'timechart span=1h avg(cpu)' without a 'by' clause, which produces a single series showing the overall average over time. Options A, C, and D would not result in a single line representing the overall average across all hosts.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The search uses 'timechart avg(cpu) by host' but the host field is null.
Why it's wrong here
If host is null, it would still produce a single series, but the field would be null, not missing.
- ✓
The search uses 'timechart span=1h avg(cpu)' without splitting.
Why this is correct
Without a 'by' clause, timechart aggregates all events into one series.
- ✗
The visualization type is set to 'Column' instead of 'Line'.
Why it's wrong here
The visualization type affects display but not the underlying data series.
- ✗
The search uses 'timechart avg(cpu) over date' without a by clause.
Why it's wrong here
'over date' is not valid syntax; timechart expects a time field implicitly.
