Rick Kellogg updated STORM-141:
-------------------------------
Component/s: storm-core
> Provide support for custom stats in Storm UI
> --------------------------------------------
>
> Key: STORM-141
> URL: https://issues.apache.org/jira/browse/STORM-141
> Project: Apache Storm
> Issue Type: New Feature
> Components: storm-core
> Reporter: James Xu
> Priority: Minor
>
> https://github.com/nathanmarz/storm/issues/27
> Something along the lines of Hadoop counters
> ----------
> gsilk: Would this be implemented as an implicit stream? It would be great to
> have global and per-task aggregations in addition to having per-bolt counters.
> ----------
> nathanmarz: gsilk: Well, besides the aggregation mechanism we need to figure
> out how the stats are sent back to nimbus, stored, etc. Not sure the current
> approach of putting the stats in ZK is a good one. Using implicit streams and
> an aggregation bolt to sum things together, and then having the aggregation
> bolt connect to nimbus and send updates might be a better design.
> ----------
> ehudl: how about using emit to a specific stream (not default) as a counter,
> do you think this is a good approach ?
> could this approach cause a memory leak? if no one is listening to this
> stream or in case you use a large amount of streams?
