Sachin Pasalkar created STORM-1343:
--------------------------------------
Summary: Add a matrices for Trident which actually counts number
of messages processed.
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
Priority: Critical
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.

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.
