Splunk: Dashboard cost of auto-refresh
A wallboard refresh interval produces more search load than expected. Count panel searches per refresh and compare aggregate runtime with concurrent viewers.
Environment and inputs: Splunk saved searches, alerts and dashboards; ownership, scheduling and action options vary by deployment and release.
Failure scenario
A wallboard refresh interval produces more search load than expected. Confirm the cause before choosing a fix.
Evidence to collect
Count panel searches per refresh and compare aggregate runtime with concurrent viewers. Record the time, affected scope and a healthy comparison interval.
Fix the confirmed cause
Use an interval suited to data arrival and combine reusable searches where behavior permits. Write the expected result first. Change one relevant setting at a time.
Check the result and hand over
Repeat the check for dashboard cost of auto-refresh using the same scope and a representative interval. Check that the symptom is resolved, expected records are present and downstream results are correct. If coverage, correctness or latency worsens, restore the recorded configuration through the agreed rollback process.
Scope and precautions
Prefer read-only access and limit queries to the relevant period or dataset. This example has not been tested on your systems. Test changes in an approved environment. Keep credentials and sensitive data out of shared evidence.
