+1 . Minor nit.
> Storm metrics feature improvement: support per-worker level metrics
> aggregation
> -------------------------------------------------------------------------------
>
> Key: STORM-2006
> URL: https://issues.apache.org/jira/browse/STORM-2006
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-core
> Affects Versions: 1.1.0
> Reporter: Jungtaek Lim
> Assignee: Jungtaek Lim
>
> Storm provides per-task level metrics which could be huge when topology has a
> number of tasks.
> Task level metric is useful for determining load balance between tasks, but
> it doesn't need to be time-series fashion.
> Before introducing topology level component like TopologyMaster for JStorm,
> we can utilize SystemBolt to aggregate task level metrics to per-worker level
> metrics.
> We should provide options and this feature should be turned off by default to
> keep backward compatibility.
