Nick Dimiduk commented on HBASE-15614:
--------------------------------------
Maybe? The pause monitor thread is reporting 2-3sec pauses that I'm not seeing
in my GC metrics. Will look a bit deeper and circle back. GC metrics wouldn't
report pauses such as this [ugly
one|http://www.evanjones.ca/jvm-mmap-pause.html]; presumably our
{{JvmPauseMonitor}} would catch this.

> 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.
