The Webalizer is a fast, free web server log file analysis program. It produces highly detailed, easily configurable usage reports in HTML format, for viewing with a standard web browser.
It was written to solve several problems that I had with currently available analysis packages. A vast majority of them were written in Perl or some other scripting language, and took forever to run. Some were not free. Some even produced wrong results, or results that were not in a format I found very useful.
In order to get the stats I wanted, in a format that I liked, I wrote The Webalizer, and have made it available here, to anyone who wants it, for any purpose. Starting as a simple Perl script with limited capabilities, it has grown into a full featured, robust and fast analysis tool, being used by thousands of systems around the globe.
