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

             Summary: Add lag in seconds JMX metrics for fether threads
                 Key: KAFKA-4797
                 URL: https://issues.apache.org/jira/browse/KAFKA-4797
             Project: Kafka
          Issue Type: Bug
          Components: metrics
    Affects Versions: 0.10.2.0, 0.10.1.1, 0.10.1.0, 0.10.0.0, 0.9.0.1, 0.9.0.0
            Reporter: Jun Ma
         Attachments: maxLag.png

Since 0.9.0.0, parameter replica.lag.max.messages was removed, replica lag time is now represent the lag between follower and leader replicas. But the metrics kafka.server:type=ReplicaFetcherManager,name=MaxLag,clientId=Replica is still representing max lag in messages between follower and leader replicas. We should change it to represent lag in time between follower and leader replicas.
