Plugins

There are various plugins available on VisualVM Plugins Center including 3rd party plugins; other plugins can be obtained as separate downloads from their respective authors. Note that the IDE integration plugins are described on the Features page.

If you need a special feature or support for a particular tool, you can implement your own plugin. It's easy and there is plenty of information and sample code available for both the NetBeans Platform and VisualVM APIs. A good place to start is the Write Plugin section.

JConsole Plugins Container. JConsole Plugins container provides support for using existing JConsole plugins (like JTop) inside VisualVM.
