VisualVM is a tool that provides a visual interface for viewing detailed information about Java applications while they are running on a Java Virtual Machine (JVM).
Programmers can also capture data about the JVM software and save the data to the local system, and then view the data later or share it with others. VisualVM is built on the NetBeans Platform; its architecture is modular and easy to extend with plugins. As of February 2015 VisualVM is actively developed.
