             Summary: AMS Storm Sink: apply change of Storm metrics improvement - worker level aggregation
                 Key: AMBARI-17909
                 URL: https://issues.apache.org/jira/browse/AMBARI-17909
             Project: Ambari
          Issue Type: Bug
          Components: ambari-metrics
    Affects Versions: 2.4.0
            Reporter: Jungtaek Lim
            Assignee: Jungtaek Lim
            Priority: Blocker


Abstraction:
This issue is for following up changes on STORM-2006: Storm metrics feature improvement: support per-worker level metrics aggregation.

Details:
With recent patches for AMS and AMS Storm sink, AMS stores task level metrics from Storm, and relevant dashboards can be configured via Grafana.

But we found that it incurs too many kinds of metrics and also too many data points published to AMS because even a topology can have lots of tasks.

In order to reduce this, I addressed STORM-2006, but it also needs AMS Storm sink and relevant Storm configurations to be changed.
