Javamelody performance & usage statistics

One of the hidden gems in the open source world is a project called Javamelody.

I've been using this since late 2009 to help refactor/modify design and code based on usage-based findings. It is not a profiler, not a click-n-fix, not a quickly-fix-your-problems tool. It is a tool to get you the information, over time, that you need to make Strategic decisions about design/code.


It gets all tiers of statistics within a single application -> the application's UI calls, business (ejb/facade/spring) calls, and sql calls.

Recently I finally submitted a patch for GWT-RPC detailed statistics I've been using for a while to help, again from a strategic point of view, refine some products.
