VisualVM Description
VisualVM monitors, troubleshoots, and diagnoses Java 1.4+ applications from a variety of vendors using jvmstat (jvmstat.com), JMX (Serviceability Agent), and Attach API. VisualVM is designed to meet the needs of all application developers, system administrators and quality engineers. VisualVM displays basic runtime information for each process: PID, mainclass, arguments passed to the java process, JVM home, JVM arguments and flags, and System properties. VisualVM monitors CPU usage of the application, GC activity and heap and metaspace / permanent memory, as well as the number of loaded classes, and running threads. VisualVM provides basic profiler capabilities to analyze application performance and memory management. Both sampling and instrumentation profiles are available.
