trying to look for an web analytics service(preferably free) which gets the usual stuff, browser, hits, OS, etc.in addition, it needs be able to track user click paths, and some how be able to tie in with my own database, maybe perhaps pass in JSON objects similar to PIWIK.  i am tracking user click paths strictly for debugging purposes so i can figure out what a user was doing to get particular errors etc.i've searched for quite a few tools and have not been able to find any, or perhaps someone can recommend that there are other better ways i can use to debug what a user has done.basically i'm looking for a web analytics tool which does what i have just described.  Clicky seems to be rather good, any other better alternatives?
