Generate Flame Graph from JFR dump with IntelliJ IDEA

Question

IDEA generates those neat flame graphs when using "Run with Java Flight Recorder".

While I know of external tools capable of this, is it possible to generate those flame graphs from existing jfr dumps with IDEA?

Answer 1

Sure, you can open any exisiting jfr report (Main menu/Run/Open Profiler Snapshot), and if it contains sampling, flame graph will also be available.
