Automatic Failover Log File Rotation

I want to check the auto failover log history, which file should I check?

OS: linux

You’ve not mentioned what version of Couchbase Server you are using.
In Couchbase Server 7.1.0 and later, the best place to look in the logs for automatic failover is the System Event Log System Events | Couchbase Docs

See IDs 6-17, System Event Reference | Couchbase Docs

thanks,

couchbase version : 6.6
