Monitoring Eclipse-plugin heap size *programatically*

Question

I know we can monitor heap size manually by ,

"Show heap status" under Window -> Preferences -> General

So is there anyway to say automatically grab the highest memory used in my eclipse plug-in? This would be convenient to me because my plug-in could run for a long time and monitoring manually is not feasible.

Thanks

Answer 1

You have here a Simple Heap Size Monitor;

long total = Runtime.getRuntime().totalMemory();
long free = Runtime.getRuntime().freeMemory();

Launched in a thread and log the total and free memory in a file.

If you encapsulate that in an eclipse plugin you could launch a custom eclipse with this activated by default and recording what you need.

Another (more simple) technique would be to attach to your eclipse session a JConsole configured to log what it monitors into a file.

JVMStat (espacially jstat) can be a good solution too.
