Most hosting companies supply you with the basic log file analysis programs. These are better than nothing, but there is so much more information you could obtain with a better program. The log analyzer I have used over the years is Sawmill, which you can find at www.sawmill.net. The amount of detail you get using this program is staggering. You can drill down to almost any level of detail. The features are too numerous to mention, so read up about them on the site. Oh, and one other important thing to mention is that you can actually get the program for free. Go to http://www.sawmill.net/testing.html for details. This is how I obtained it. All it takes is a little of your time.
