[jira] [Created] (KAFKA-921) Expose max lag mbean for consumers and replica fetchers

Joel Koshy created KAFKA-921:
--------------------------------

             Summary: Expose max lag mbean for consumers and replica fetchers
                 Key: KAFKA-921
                 URL: https://issues.apache.org/jira/browse/KAFKA-921
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 0.8
            Reporter: Joel Koshy
             Fix For: 0.8


We have a ton of consumer mbeans with names that are derived from the consumer id, broker being fetched from, fetcher id, etc. This makes it difficult to do basic monitoring of consumer/replica fetcher lag - since the mbean to monitor can change. A more useful metric for monitoring purposes is the maximum lag across all fetchers.
