>                 Key: KAFKA-10106
>                 URL: https://issues.apache.org/jira/browse/KAFKA-10106
>             Project: Kafka
>          Issue Type: Improvement
>            Reporter: NIKHIL
>            Priority: Minor
>   Original Estimate: 24h
>  Remaining Estimate: 24h

> ReplicaManager!becomeLeaderOrFollower handles the LeaderAndIsr request, StateChangeLogger logs when this request is handled, however it can be useful to log when this calls ends and record the time taken, can help operationally. 
> Proposal is to ReplicaManager!becomeLeaderOrFollower start measuring the time before the `replicaStateChangeLock` is acquired and log before the response is returned.
