Well the usual way of doing performance measurement is to log the metrics you
want to track and then use tools like Splunk to get the info you need for
measuring performance.
The above approach will require some work. The other simpler way would be to
have a State which can keep track of the metrics you need. Then you can send
the metrics to that state and use drpc query or other methods to get the info
you need.

Thanks Nikhil.
Since Storm UI doesn't give the clear info then for what purpose Storm UI can
be used for? basically i need to know if there is any use of monitoring UI
during my load & stress testing of STORM.

And if you really want to see what messages are getting exchanged, configure
the root logger to show all the logs, you will see lot of messages related to
master-coord, ack stream, batch stream, success stream etc..

In your UI, on the topology's page, scroll to the bottom, click, "show system
stats".
Now, every bolt is shown. List out everything you have. Whose numbers are
changing?
Thank you for your time!

Hi All,
I am looking at STORM UI to analyze the performance of my trident topology..
what i have found strange is that the count under"emitted" & "transferred"
column under "Topology Stats" table keeps on increasing... To my surprise, i
had kept zero messages in my Kafka brokers(source for spout) but still can see
Emitted counter ramping up..
is this common scenario?
