UseItBetter for Flex

I have big Flex application and want to add analitics gather to it. I try to use this: http://useitbetter.com/ but it seems that it don't work with开发者_运维问答 Flex

Maybe you know something like this that will work with Flex?

Thanks Vladimir

I've personally used Google Analytics in the past to do this. It has worked out pretty darn well :)
