> Key: STORM-1719
> URL: https://issues.apache.org/jira/browse/STORM-1719
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-core
> Affects Versions: 1.0.0, 2.0.0
> Reporter: Jungtaek Lim
> Assignee: Jungtaek Lim
> Fix For: 1.1.0
>
>
> Apache Storm has two REST APIs for showing topology stats,
> /api/v1/topology/:id and showing component stats,
> /api/v1/topology/:id/component/:component.
> Both of APIs shows metrics aggregated by topology or each component.
> It helps determining traffics between component to component, which is good
> for many topologies. But if users use their own topology which utilizes lots
> of streams, they may want to see topology stats in detail - in point of
> stream's view.
> We already have visualization API to show the traffics between stream to
> stream, but it's internal API, and contains only transferred, and it shows
> non-aggregated result so users need to aggregate theirselves.
