>
> We borrowed Hadoop's JvmPauseMonitor some time ago. On HADOOP-14960 (Add GC time percentage
monitor/alerter), Hadoop added a new GcTimeMonitor, which seems useful:
> {code}
> /**
>  * This class monitors the percentage of time the JVM is paused in GC within
>  * the specified observation window, say 1 minute. The user can provide a
>  * hook which will be called whenever this percentage exceeds the specified
>  * threshold.
>  */
> {code}
