@priyank5485 Yes I see the tables don't get populated if lag responses are
empty, but we still end up with the div markup on the page. It seems that this
may be an area where other spouts could put their stats in the future. Could
you call the div topology-spout-stats, and put a comment in the html that says
it gets populated if stats are available?
> Provide a bin script to check consumer lag from KafkaSpout to Kafka topic

> We store kafkaspout offsets in zkroot + id path in zookeeper. Kafka provides
> a utility and a protocol request to fetch latest offsets into topic
> {code}
> example:
> bin/kafka-run-classh.sh kafka.tools.GetOffsetTool
> {code}
> we should provide a way for the user to check how far the kafka spout read
> into topic and whats the lag. If we can expose this via UI even better.
