> We currently expose our jmx metrics via a json dump in a servlet at /jmx. You 
> get all or nothing (You can add a '?description=true' to get a description 
> for each metric published but that is it).
> A means of being able to query by metric or by a set of metrics would make 
> graphing easier to do, especially over http dumping json. In particular, our 
> [~appy] is trying to put up pages that give insight into current state of 
> replication.
> Related, HBASE-11747 ClusterStatus is too bulky, is about how whenever we 
> need a metric 'exposed', our only means is by bulking out the heartbeat 
> adding payload on each message we send the server (In the issue, w/ 1M 
> regions, each RS is sending 100MB of 'status' every second). We need to undo 
> metrics collection from clusterstatus function
> Bonus if able to compress/cache payloads, security, etc.
