[jira] [Created] (YARN-262) add event dispatcher metrics

Thomas Graves created YARN-262:
----------------------------------

             Summary: add event dispatcher metrics
                 Key: YARN-262
                 URL: https://issues.apache.org/jira/browse/YARN-262
             Project: Hadoop YARN
          Issue Type: Improvement
    Affects Versions: 0.23.5
            Reporter: Thomas Graves


It would be useful to see metrics about the event dispatchers.  Things like how big the queues are, how many in them, perhaps rate or processing, etc..  Perhaps be able to dump them out via jmx.
