SQL Server: Server restart counter resets
A monitoring chart shows a dramatic improvement after a restart. Compare instance uptime with cumulative counter reset boundaries.
Environment and inputs: SQL Server operational monitoring; availability groups, SQL Agent and host-level metrics depend on edition, service and deployment.
Failure scenario
A monitoring chart shows a dramatic improvement after a restart. Confirm the cause before choosing a fix.
Evidence to collect
Compare instance uptime with cumulative counter reset boundaries. Record the time, affected scope and a healthy comparison interval.
Fix the confirmed cause
Segment time series across resets and use interval rates that do not turn reset counters into negative activity. Write the expected result first. Change one relevant setting at a time.
Check the result and hand over
Repeat the check for server restart counter resets 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.
