     [ https://issues.apache.org/jira/browse/KAFKA-542?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Joel Koshy updated KAFKA-542:
-----------------------------

    Attachment: KAFKA-542-v1.patch

Patch overview:

1 - I sent a mail to metrics-user group asking when 3.0.0 will be made
  available in mvn central. For now, I just did a local build off this:
  https://github.com/codahale/metrics.git -
  10ccc80c0f574f104c4745a1ffa24af0ea92efbf
  Added metrics-annotation-3.0.0-10ccc80c0.jar
  metrics-core-3.0.0-10ccc80c0.jar to core/lib (which cannot be included in
  the diff).
2 - Made couple of changes due to slight differences in 3.0.0 API.
3 - Fixed a small bug in the CSV reporter startup.
4 - Provided a sample config in server.properties.

> metrics 3.0.0 fixes some issues with the csv reporter that affect 0.8
> E.g., with metrics 2.1.3 we would just have NumDelayedRequests.csv but with 3.0.0 we would have kafka.server.ProducerRequestPurgatory.NumDelayedRequests.csv and kafka.server.FetchRequestPurgatory.NumDelayedRequests.csv
