Hi Igor,

Just to clarify, are you saying that running storm-kafka-monitor from command 
line with the arguments you pasted returns the spout lags correctly ? Also, can 
you confirm if you are running in a secured setup or not ?

a second.

Hello!
  You can check how your topic is consumed  and its health via the scripts:
./kafka-consumer-groups.sh --new-consumer --bootstrap-server <your-broker>:6667 
--list
 ./kafka-consumer-groups.sh --new-consumer --bootstrap-server 
<your-broker>:6667 --describe --group <your-group>

I hope it helps.

Yes, topology process data and works fine.
I couldn't find any exceptions in storm logs.   access-web-ui.log contains only 
these lines

Hi Igor,

When you say topology is working fine do you mean you see data flowing? Can you 
try to look up the logs for ui server and paste relevant lines here if any?

I've launched topology with new kafka spout. Topology by it self working fine, 
but looking at storm UI I see kafka-monitor exception:
Unable to get offset lags for kafka. Reason: 
org.apache.kafka.shaded.common.errors.TimeoutException: Timeout expired while 
fetching topic metadata

Maybe I forgot to configure something, but then how topology reads messages?
