    @abhishekagarwal87 I am excited to see your screenshot as well. Also, I am 
curious as why you chose to use 
https://github.com/apache/storm/blob/master/storm-core/src/jvm/org/apache/storm/metric/internal/LatencyStatAndMetric.java
 over 
https://github.com/apache/storm/blob/master/storm-core/src/jvm/org/apache/storm/metric/internal/CountStatAndMetric.java?

> I envision being able to browse the Storm UI and see where queues of tuples 
> are backing up.
> Today if I see latencies increasing at a bolt, it may not be due to anything 
> specific to that bolt, but that it is backed up behind an overwhelmed bolt 
> (which has too low of parallelism or too high of latency).
> I would expect this could use sampling like the metrics reported to the UI 
> today, and just retrieve data from netty about the state of the queues. I 
> wouldn't imagine supporting zeromq on the first pass.
