-------------------------------

             Summary: Add sensors for NumOfflineThread, FetchRequestRate and 
FetchRequestLocalTime in the follower broker
                 Key: KAFKA-7191
                 URL: https://issues.apache.org/jira/browse/KAFKA-7191
             Project: Kafka
          Issue Type: Improvement
            Reporter: Dong Lin
            Assignee: Dong Lin


It will be useful to have NumOfflineThread to monitor the number of offline 
thread (e.g. ReplicaFetcherThread) in the broker so that system admin can be 
alerted when there is offline thread.

And we also need metrics for FetchRequestRate and FetchRequestLocalTime in the 
follower broker to monitor and debug the data replication performance.
