A master-eligible node rejoined the cluster after a restart. Brief master elections can occur during rejoin and might affect cluster coordination.

The following is an example of what you might see when this insight is triggered. Real insights use live data and links from your deployment or cluster.
A master-eligible node rejoined the cluster: es-data-01.
AutoOps shows different recommendations depending on how their conditions match your deployment or cluster.
Investigate node restart
Condition: Always shown for this insight.
Review Elasticsearch and host logs for es-data-01 around the restart time for out-of-memory errors, garbage collection failures, fatal exceptions, or planned maintenance. Confirm cluster health is green and recovery has finished.
When a master-eligible node restarts, it is temporarily absent from master elections. The cluster might elect a new master if the active master was on the restarted node. Brief coordination delays are possible during rejoin.
Planned rolling restarts are usually low risk if quorum is maintained throughout.
