SPLK-1002 Advanced Visualization and Lookups Practice Question
A Splunk admin is tasked with creating a dashboard that shows the average response time per server over the last hour, updated every 60 seconds. The data comes from a sourcetype 'app_log' with fields: server, response_time. The admin wants to use a single search with a timechart and set the dashboard's time range picker to 'Last 60 minutes'. However, the chart shows only one data point (the average for the entire hour) instead of per-minute intervals. What is the most likely cause and solution?
⚠ Common exam trap
Splunk often tests the default behavior of `timechart` without a `span`, tricking candidates into thinking the issue is with the time range picker or search mode rather than the missing span parameter.
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 timechart command does not have a span specified; add | timechart span=1m avg(response_time) by server
The `timechart` command without an explicit `span` defaults to a single bucket for the entire search time range when the range is fixed (e.g., 'Last 60 minutes'). By adding `span=1m`, you force the command to create 1-minute buckets, producing a data point per minute. This is the most direct fix for the described behavior.
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 dashboard uses a summary index; switch to a base search
Why it's wrong here
Summary index not relevant to the span issue.
- ✗
The search is not set to real-time; change to a real-time search
Why it's wrong here
Real-time search not required; refresh interval suffices.
- ✗
The dashboard time range picker is set to 'All time'; change to 'Last 60 minutes'
Why it's wrong here
Already set correctly; the issue is the span.
- ✓
The timechart command does not have a span specified; add | timechart span=1m avg(response_time) by server
Why this is correct
Specifying span=1m creates per-minute buckets.
