ASF GitHub Bot commented on STORM-433:
--------------------------------------
Github user nathanmarz commented on the pull request:
https://github.com/apache/incubator-storm/pull/236#issuecomment-53480325
A few things:
1. I made a comment about inserting a type hint to avoid reflection
2. To be clear, the only queue you're monitoring here is the receive queue
for executors?
3. I need to be convinced more that the interactions with the
DisruptorQueue are thread-safe. This is critical code, so we have to be extra
careful.

> 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.
