Analyzing with JDK Mission Control

JDK Mission Control (JMC) is the graphical tool for analyzing JFR recordings.

It opens a .jfr file and turns raw events into navigable views: hot methods, GC behavior, lock contention, allocation, and more. It also includes an Automated Analysis page that flags likely problems.

JMC is a standalone download (it was unbundled from the JDK after JDK 8).

Grab it from the Adoptium or Oracle JMC builds, launch it, and open your .jfr file with File > Open File. No agent or restart of your app is needed — you analyze the already-captured recording.
