Storm UI Issue

HI ALL ,

Kindly help me to sort out out the issue with storm UI.

In our topology , we have a Kafka spout and 2 bolts (which doesn't emit any
downstream tuples).
My bolts jsut process the incoming tuples .And executors to Kafka spout and
bolts are set to one .
When running our topology , However my bolts are not emitting any
downstream tuples,but still i am able to see the "Emitted and Transferred"
values in bolts section .I hope this not the expected behaviour . Kndly any
one help me .
Please let me know ,in case of more information needed .



Regards ,
Nanda .

Do you have system stats enabled?  The numbers you see are aggregates across all of the bolts, and all of the other things they could be sending messages to.  If you have system stats enabled on the UI you could be seeing metrics or ack messages being sent around.  It is also possible that storm has a bug in it that we are not filtering some system stats properly.
