Andrew Purtell commented on HBASE-15614:
----------------------------------------

bq.  In any case, we need to differentiate the JVM pause metrics for RS / Rest or Thrift based
on the server type.If not, the approach in the patch seems fine.  +1.
Thanks Enis.

> We have {{JvmPauseMonitor}} for detecting JVM pauses; pauses are logged at WARN. Would
also be good to expose this information on a dashboard via metrics system -- make it easier
to get this info off the host and into a central location for the operator.
