------------------------------
Summary: Add more metrics to DisruptorQueue
Key: STORM-1007
URL: https://issues.apache.org/jira/browse/STORM-1007
Project: Apache Storm
Issue Type: Bug
Reporter: Li Wang
Assignee: Li Wang
The metrics of the queues for each component are very helpful to reason about
the performance issues of a topology.
For instance, for the applications with strong time constraint (e.g., threat
detection), if the elements in the input queue of a bolt have a long sojourn
time, it indicates that the user should increase the parallelism of that bolt
to reduce the processing delay.
However, the metrics on the DisruptorQueue currently available are limited.
More useful metrics, such as average sojourn time and average throughput are
expected.
