The Server Side published an interesting article on AOL And Performance Monitoring. This is a good - if short - piece on Aspects and performance. I wish the article talked about where AOP is inappropriate.

I've been looking lately at Glassbox.com. Glassbox is an open-source project (GPL) of what seems to be an implementation of this kind of AOP technique. I would like to add something like Glassbox to my PushToTest TestMaker open-source test tool to do root cause anlysis. While a performance test is generating concurrent load on an application TestMaker would correlate the Glassbox observations with test cases being run. You could then say "What was going on in my web app while testcase #13 was running?"
