SPLK-1002 Advanced Visualization and Lookups Practice Question
You are a Splunk power user at a manufacturing company. You have created a timechart that shows machine temperature readings over time. The data is indexed with timestamps every minute, but the timechart shows gaps where no data exists because some machines may not report at all times. You want to fill the gaps with 0 values to avoid misleading visualizations. The current search is: index=manufacturing sourcetype=temperature | timechart span=1h avg(temp) by machine. Which modification to the timechart command will fill the gaps with 0?
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
✓
timechart span=1h usenull=t
Usenull=t fills null values with 0. Option A is incorrect because cont=t ensures continuous time buckets but does not fill nulls with 0. Option B is incorrect because limit=0 does not affect null filling. Option D is incorrect because usenull=f leaves gaps, and useother=f is irrelevant.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
timechart span=1h cont=t
Why it's wrong here
cont=t ensures continuous time range but does not fill nulls.
- ✗
timechart span=1h limit=0
Why it's wrong here
limit=0 includes all series but does not fill nulls.
- ✓
timechart span=1h usenull=t
Why this is correct
usenull=t fills nulls with 0.
- ✗
timechart span=1h usenull=f useother=f
Why it's wrong here
usenull=f leaves gaps, useother=f is unrelated.
