SPLK-1002 Advanced Searching and Statistics Practice Question
A Splunk admin is responsible for a search dashboard that displays real-time statistics of application errors. The search uses 'index=app sourcetype=error | timechart count by severity span=5m'. Users report that the dashboard is slow and often times out. The environment has 4 indexers and the data volume is about 500 GB/day. The admin wants to improve performance without changing the dashboard's output. Which step should they take?
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
✓
Create a summary index that runs every 5 minutes to pre-aggregate error counts by severity, and modify the dashboard to search the summary index.
Creating a summary index that pre-aggregates error counts by severity every 5 minutes reduces the amount of data scanned in real-time, improving performance without changing the dashboard's output. Option A is wrong because using 'bucket' and 'stats' with streaming commands still requires scanning all raw events; it does not precompute results and may not significantly reduce I/O. Option C is wrong because limiting the time range alters the dashboard's displayed data (e.g., less historical context), which violates the requirement to keep the output unchanged. Option D is wrong because search acceleration (e.g., data model acceleration) creates summaries for specific data models, not arbitrary field aggregations; it may not target the 'severity' breakdown efficiently and can consume significant resources.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Replace timechart with 'bucket _time span=5m | stats count by _time, severity' and add streaming commands.
Why it's wrong here
Similar resource usage; not a significant improvement.
- ✓
Create a summary index that runs every 5 minutes to pre-aggregate error counts by severity, and modify the dashboard to search the summary index.
Why this is correct
Reduces the amount of data scanned in real time.
- ✗
Limit the time range to the last 1 hour instead of 24 hours.
Why it's wrong here
Does not meet the requirement of not changing the output (the dashboard may need 24h).
- ✗
Enable search acceleration for the index.
Why it's wrong here
Search acceleration speeds up historical searches but not real-time searches.
