Subject [jira] [Created] (ZOOKEEPER-3092) Pluggable metrics system for ZooKeeper
Date Tue, 17 Jul 2018 22:10:00 GMT
Michael Han created ZOOKEEPER-3092:

             Summary: Pluggable metrics system for ZooKeeper
                 Key: ZOOKEEPER-3092
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3092
             Project: ZooKeeper
          Issue Type: New Feature
          Components: metric system
            Reporter: Michael Han

ZooKeeper should provide a pluggable metrics system such that various metrics can be collected
and reported using different approaches that fit production monitoring / alert / debugging
Historically ZooKeeper provides four letter words and JMX which exposes certain stats / metrics
but they are not very flexible in terms of programmatically accessing metrics and connecting
metrics to different reporting systems.

There are other projects that's already doing this which can be used for reference, such as
bookkeeper metrics service providers and hadoop metrics2.
