@yonzhang, Yes, the data model abstract the heap usage and gc pause time,
it also works for G1 GC
> Enable GC Log monitoring for important service like hadoop namenode

> Affects Versions: 0.3.0
> Reporter: Libin, Sun
> Assignee: Libin, Sun
>
> Garbage Collection Monitoring refers to the process of figuring out how JVM
> is running GC.
> When GC happened, JVM will stop the application from running to execute a GC,
> every thread except for the threads needed for the GC will stop their tasks.
> The interrupted tasks will resume only after the GC task has completed, the
> stop interval is known as "stop-the-world"
> For service like namenode, GC will affect the performance, especially full
> GC, we should avoid full GC and if full GC happened, we should detected it
> ASAP and sent out alert
