---------------------------------
Summary: Give users visibility to the depth of queues at each bolt
Key: STORM-433
URL: https://issues.apache.org/jira/browse/STORM-433
Project: Apache Storm (Incubating)
Issue Type: Wish
Reporter: Dane Hammer
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.
