Blog statistics

I run small wordpress blog with 3-5 users. People add/edit/remove and read content all the time… What I want is to be able to see some sort of statistics…. which posts/pages are most popular, most updated, commented… which external links are the ones clicked most times… etc….

is there a plugin (not external service) to achieve that?

Piwik is similar to Google Analytics, but you install on your own server.

Also- I’ve seen a private internal intranet site that was tracked on Google Analytics. It was certainly not publicly or search engine accessible, so it is possible to at least use GA on a private site if you’re curious to investigate further.
