Java Mission Control (JMC) is an open-source tool for monitoring, managing, and profiling Java applications. It provides a graphical user interface built on Eclipse RCP for connecting to Java applications via JMX, analyzing Java Flight Recorder (JFR) data, and performing heap analysis. The application features a modular OSGi plugin architecture with core libraries for shared functionality (unit handling, flight recorder parsing, JMX common) and application plugins for specific features (flight recorder UI, JMX console, browser, agent). Key capabilities include real-time MBean monitoring, flight recording control and analysis, heap dump analysis, and custom rule-based diagnostics.
