VisualVM Profiler

Recent change notes:

1.0.0 (2008-12-08)
- Support for VisualVM 1.1
- Autodetect Java version when choosing the profiler interface to use (although officially VisualVM supports only Java 6 and 7)

0.4.2 (2008-11-26)
- Fixed possible NPE if the MainClass returned by IDEA was null

0.4.1 (2008-11-24)
- Fixed inconsistent naming of profiler actions (IDEA 8 only)
- Fixed the profiler actions appearing in every file's context menu (IDEA 8 only)

0.4.0 (2008-11-24)
- Compatible with IDEA 8
- Uniquely identify the application launched by IDEA

0.3.0 (2008-11-12)
- Memory profiling
- Settings are copied to VisualVM's user interface
- Saved space in the run configuration dialog by moving help texts to tooltips

0.2.0 (2008-11-09)
- Works with the bundled VisualVM which comes with JDK 6 Update 7 and above
- Detects bundled VisualVMs automatically, in which case no configuration is necessary
- Should work also with Linux and Mac (not tested, also not sure about 64 bit JVMs)
- Defaults to jdk15 profiler interface for better compatibility (hardcoded)
- Warns about invalid configuration

0.1.0 (2008-11-06)
- Initial release
- CPU profiling (Windows Java 6 only)

Known issues
- VisualVM may freeze if the application finishes execution before its window opens up in VisualVM. A workaround is to add Thread.sleep(1000) or a longer delay to the beginning of the main() method of the profiled application.

Future plans
- A button for opening the currently running (non-profiled) program in VisualVM, so that the user will not need to manually select the program from VisualVM's list of all running Java programs
- Integration with NetBeans IDE's profiler if it has benefits over VisualVM (they both use internally the same NetBeans Profiler)

General usage instructions:

If you have JDK 6 Update 7 or higher configured in IDEA:
1. Click the "Profile CPU" button (next to the "Run" and "Debug" buttons) to begin profiling.

Otherwise you need to install VisualVM separately:
1. Download VisualVM 1.0.1 from https://visualvm.dev.java.net/download.html
2. Install it to "C:/Program Files/visualvm"
3. Configure the plugin (Settings | VisualVM) by pointing it to "C:/Program Files/visualvm"
4. Click the "Profile CPU" button (next to the "Run" and "Debug" buttons) to begin profiling.

Version 1.0.0 of this plugin is not compatible with VisualVM 1.2, and this plugin is not being maintained. Anybody is free to fork the plugin's code at http://github.com/orfjackal/visualvm4idea and continue its maintenance.

It won't run on my Windows machine nor on my Mac. VisualVM comes up, it says something about a taking a snapshot which seems to do nothing, and IntelliJ reports this error:

Hi,

I am getting following error after clicking "Profile Memory"--

This plugin successfully launches VisualVM and my application (in that order), but my app doesn't appear in the list of apps to profile in VisualVM (under Local). The only app I can profile is VisualVM itself. Sometimes I get a "No response from VisualVM" exception, but not every time. The configuration seems to have worked OK, since the "Startup/Connection" settings appear to be correct. Any ideas?

The "No response from VisualVM" exception is not dangerous. Just a little timeout, because VisualVM did not respond quickly enough.

First time I ran it, visualvm needed to callibrate and intellij reported this exception:

Try if version 0.4.2 fixes that problem. I was not able to reproduce that NPE myself, so I can't verify the fix, but the part which I fixed should be the only possible cause of that NPE.
