Does anyone know of a Cocoa/Obj-C library that can be used to gather application usage data

Question

I would like to be able to gather info like how often certain windows are opened, what types of user data are accessed, how often menu items are clicked, etc. Does anyone know of a 3rd party (open source or commercial) Cocoa/Obj-C library or plugin that would allow me to gather this info?

Answer 1

I have used pinch media in the past, and they merged with Flurry. Library was simple to use and was setup in around 40 minutes.
