Enis Soztutar commented on HBASE-15614:
---------------------------------------
Yes please. I was thinking about this as well. We need how many times we paused
and for how long according to the JVM pause monitor.
We have seen a couple of cases where the OS pauses the process for ~10-30
seconds, and GC logs or GC metrics do not show any activity. OS can pause the
process for various reasons swap, or bad disk drivers.

> Project: HBase
> Issue Type: Improvement
> Components: metrics, regionserver
> Reporter: Nick Dimiduk
>
> 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.
