I will do that Eric. I am using
https://github.com/apache/storm/blob/master/storm-core/src/jvm/org/apache/storm/metric/internal/LatencyStatAndMetric.java
to store the windowed values. It is easy to add the instantaneous values in
the result map so that is not a problem. I will put a screenshot and the PR
soon. May be that will clear the confusion.

> Key: STORM-433
> URL: https://issues.apache.org/jira/browse/STORM-433
> Project: Apache Storm
> Issue Type: Wish
> Components: storm-core
> Reporter: Dane Hammer
> Assignee: Kyle Nusbaum
> Priority: Minor
>
> 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.
