Arvid Heise commented on FLINK-13550: ------------------------------------- Merged into master for 1.13 as e9385051cd2ac7110f02b361ac503d9153441f9f..12a99e8fe84c28fb250028b4fde4025ec9dc00c9. Thanks [~dmvk] and [~afedulov] for your contributions! > 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 Morávek > Assignee: Alexander Fedulov > Priority: Major > Labels: pull-request-available > > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
