OpenJDK Mission Control
JDK Flight Recorder (JFR) is an agent in the HotSpot JVM that provides a low-overhead, production-ready sampling profiler and monitoring tool. JFR is very similar to the IBM Java Health Center agent for the J9 JVM.
JDK Mission Control (JMC) is a project by OpenJDK that provides a GUI client to review JFR collections.
