David Moravek commented on FLINK-13550:
---------------------------------------
Hi [~xintongsong], we already use this in our internal build and I'm definitely
planning to contribute this back. It'd be helpful if you could assign the issue
to me. I'll try to send an initial PR with the rest endpoint within next week.
> Support for CPU FlameGraphs in new web UI
> -----------------------------------------
>
> Key: FLINK-13550
> URL: https://issues.apache.org/jira/browse/FLINK-13550
> Project: Flink
> Issue Type: New Feature
> Components: Runtime / REST, Runtime / Web Frontend
> Reporter: David Moravek
> Priority: Major
>
> For a better insight into a running job, it would be useful to have ability
> to render a CPU flame graph for a particular job vertex.
> Flink already has a stack-trace sampling mechanism in-place, so it should be
> straightforward to implement.
> This should be done by implementing a new endpoint in REST API, which would
> sample the stack-trace the same way as current BackPressureTracker does, only
> with a different sampling rate and length of sampling.
> [Here|https://www.youtube.com/watch?v=GUNDehj9z9o] is a little demo of the
> feature.
