Ask HN: Tracking software for tracking all outbound links on a site?

Anyone know of a tracking software that I can integrate with every link on my site being clicked on (auto coded in)?

Some something like Hacker News and there are links being generated all the time, I want to be able to track number of clicks and various data surrounding that. Most web analytics kind of track somewhat like it but I am looking for specifically link tracking structure. Open source would be great.

Bit.ly analytics type is a bit lacking.
