stack commented on HBASE-7633:
------------------------------
Looks like we don't doc callQueueLen in refguide, not currently. If we added
it Joey, would that do to close this issue? (Elliott, what is the metric's
full name and I'll add the doc.)
> Add a metric that tracks the current number of used RPC threads on the
> regionservers

> One way to detect that you're hitting a "John Wayne" disk[1] would be if we
> could see when region servers exhausted their RPC handlers. This would also
> be useful when tuning the cluster for your workload to make sure that reads
> or writes were not starving the other operations out.
