> 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.
