[jira] [Commented] (KAFKA-604) Add missing metrics in 0.8

["Jun Rao (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/KAFKA-604?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13580890#comment-13580890 ] 

Jun Rao commented on KAFKA-604:
-------------------------------

This patch no longer applies. Thinking a bit. We probably just need to get the following stats in jmx. The per topic level flush time is probably overkill.

Producer: droppedMessageRate per topic 

ReplicaManager: partition count on the broker

> It would be good if we add the following metrics:
> Producer: droppedMessageRate per topic
> ReplicaManager: partition count on the broker
> FileMessageSet: logFlushTimer per log (i.e., partition). Also, logFlushTime should probably be moved to LogSegment since the flush now includes index flush time.
