> Key: STORM-1343
> URL: https://issues.apache.org/jira/browse/STORM-1343
> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-core
> Affects Versions: 0.10.0
> Reporter: Sachin Pasalkar
> Attachments: Re Trident topology showing improper values in UI.msg
>
>
> If we keep trident topology running without pumping any messages in Kafka.
> Storm UI still show increased count. After some investigation we found one
> blog mentioning that its not actual processed message count
> https://github.com/miguno/kafka-storm-starter/issues/5
> As user, its very confusing what is this count and some time it gets
> misinterpreted. We have seen core storm is showing the count correctly. As
> trident is abstract level of core storm can't we use those matrices?
> We also found a blog where user can manually add the matrices to his code
> which will come up to the Storm UI.
> http://www.bigdata-cookbook.com/post/72320512609/storm-metrics-how-to
> Can we implement processed tuple matrices in trident directly? That will
> helful to end user in understanding what is topology doing & what needs to
> done to increase EPS of particular component.
