-------------------------------------
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.
