Subject [jira] [Commented] (ZOOKEEPER-3092) Pluggable metrics system for ZooKeeper
Date Wed, 18 Jul 2018 18:38:00 GMT

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

> 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.
