> 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.
