-------------------------------------

             Summary: Storm metrics sink should include worker host and port to metric name
when metrics are coming from SystemBolt
                 Key: AMBARI-17249
                 URL: https://issues.apache.org/jira/browse/AMBARI-17249
             Project: Ambari
          Issue Type: Improvement
          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.
