Joey Echeverria commented on HBASE-7633:
----------------------------------------
callQueueLen is close I think, but I'm not sure how that translates into tuning
hbase.regionserver.handler.count. Do we have a good example of interpreting
that value?
> Add a metric that tracks the current number of used RPC threads on the

> 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.
