Assignee: (was: Denis Chudov)
> Implement lightweight profiling of messages processing
> ------------------------------------------------------
>
> Key: IGNITE-10418
> URL: https://issues.apache.org/jira/browse/IGNITE-10418
> Project: Ignite
> Issue Type: New Feature
> Reporter: Alexey Scherbakov
> Priority: Major
> Labels: IEP-35
>
> There is a lack of capabilities to identify bottlenecks without extensive
> profiling on server and client side (JFR recording, sampling profilers,
> regular thread dumps, etc), which is not always possible. Even having
> profiling data not always helpful for determining several types of
> bottlenecks, for example, if there is a contention on single key/partition.
> Lightweight message profiling will allow to track each message execution, to
> collect a statistics of execution in executors for each grid node and for all
> nodes, collect histograms distributed by waiting/execution time for each type
> of message.
> We need to implement:
> # histogram metrics for message execution time, queue waiting time, queue
> size at the moments of queue add and execution start, with distribution by
> message type;
> # Dumping of messages if it’s execution/waiting time exceeds some threshold
> timeout, i.e.
> {code:java}
