> Components: ambari-metrics
> Affects Versions: 2.4.0
> Reporter: Jungtaek Lim

>
> Background: SystemBolt is reserved component for each worker which exposes
> worker level metrics like Memory, GC, and uptime, and so on.
> All SystemBolts have -1 as task id, so identifying SystemBolt components to
> task id as same as normal components will fail.
> Since each worker is identified by (worker host, port) pair, we can add
> hostname and port to metric name to make metric name unique.
> Since it's only for SystemBolt, instead of adding hostname and port to all of
> metrics, we can add these to specific metrics which are coming from
> SystemBolt.
