Enrico Olivelli commented on ZOOKEEPER-3092:
--------------------------------------------
For me it is okay to have a zookkeeper specific metrics system/API.
Let's start with a PR with the API.
I will create a bunch of subtasks.
It would be very good to do one step at a time
> 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
> Priority: Major
>
> 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 needs.
> 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.
