Well, the best way on getting site wide statistics is by using a weblog parser. A good one to try is awstats, which can provide some general stats on your website. It requires apache, but you should be using that anyways ;)

If you are looking for an alternative solution, I have also written a weblog parser that has some additional functionality in some areas. It has your standard browser/os/hits/graphs/etc, plus a few unique features like a hierarchy view. It also requires apache.
