Yu Chen resolved FLINK-33325. ----------------------------- Release Note: Since Flink 1.19, we support profiling the JobManager/TaskManager process interactively with [async-profiler](https://github.com/async-profiler/async-profiler) via the Flink Web UI, which allows users to create a profiling instance with arbitrary intervals and event modes, e.g ITIMER, CPU, Lock, Wall-Clock and Allocation. Flink users can complete the profiling submission and result export via Flink Web UI conveniently. For example, - First, users should find out the candidate TaskManager/JobManager with performance bottleneck for profiling, and switch to the corresponding TaskManager/JobManager page (profiler tab). - Users can submit a profiling instance with a specified period and mode by simply clicking on the button `Create Profiling Instance`. (The description of the profiling mode will be shown when hovering over the corresponding mode.) - Once the profiling instance is complete, the user can easily download the interactive HTML file by clicking on the link. **More Information** - [Documents](https://nightlies.apache.org/flink/flink-docs-release-1.19/docs/ops/debugging/profiler/) - [FLIP-375: Built-in cross-platform powerful java profiler](https://cwiki.apache.org/confluence/x/64lEE) Resolution: Resolved > FLIP-375: Built-in cross-platform powerful java profiler > -------------------------------------------------------- > > Key: FLINK-33325 > URL: https://issues.apache.org/jira/browse/FLINK-33325 > Project: Flink > Issue Type: Improvement > Components: Runtime / REST, Runtime / Web Frontend > Affects Versions: 1.19.0 > Reporter: Yu Chen > Assignee: Yu Chen > Priority: Major > Fix For: 1.19.0 > > > This is an umbrella JIRA of > [FLIP-375|https://cwiki.apache.org/confluence/x/64lEE] -- This message was sent by Atlassian Jira (v8.20.10#820010)
