> 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.
