> 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 Morávek
> Assignee: Alexander Fedulov
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.13.0

>
> 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.
