jmc-flame-view

Community collaboration to provide a view that renders stacktrace selections as flame graphs in Mission Control.

Note that this code is now contributed to the JMC project.

For the latest version, check the JDK Mission Control repo at https://github.com/openjdk/jmc.

Flame Graph View Example

This plug-in should provide a good example for how to use JavaScript visualization technologies to render complex information from java flight recordings in JDK Mission Control.

To start working on the flame-view, and to test the flame-view:

  1. First import the JMC project into Eclipse.
  2. Don't forget to import the launchers.
  3. Copy and rename one of the launchers (for example the JMC RCP plug-ins launcher), to have your own launcher configuration.
  4. Import the two eclipse projects (the plug-in and the feature projects) from this repo into your eclipse.
  5. Add org.openjdk.jmc.feature.flightrecorder.ext.flamegraph to the features to launch in your launcher.
  6. Launch JMC from within Eclipse with your new launcher.

To use the view in JMC:

  1. Go to Window | Show View | Other...
  2. Select Mission Control / Flame View
  3. Put the view where you want it, and select something in the UI that normally has a stack trace aggregate, for example something from the Memory page, or something from the Method Profiling page
