Webalizer

Webalizer is a Web server log file analysis tool that comes installed by default on Red Hat/Fedora Linux. Each night, Webalizer reads your Apache log files and creates a set of Web pages that enable you to view Web surfer statistics for your site. The information provided includes a list of your Web site's most popular pages sorted by hits along with traffic graphs showing the times of day when your site is most popular.

How to View Your Webalizer Statistics

Fedora creates an add-on configuration file named /etc/httpd/conf.d/webal-izer.conf that includes all the necessary Apache commands for Webalizer to work. As in the case of the MRTG add-on file mentioned above, you have to edit it to allow access to the Webalizer pages from locations other than the Linux console. You also have to restart Apache to make the changes take effect.

By default, Webalizer places its index page in the directory /var/www/html/usage and allows you to view your data by visiting the URL http://server-ip-address/usage.

The Webalizer Configuration File

Webalizer stores its configuration in the file /etc/webalizer.conf. The default settings should be sufficient for your Web server, but you may want to adjust the directory in which Webalizer places your graph statistics. This can be adjusted with the OutputDir directive in the file. After adjustments, Webalizer functions with few annoyances; however, be aware that running in quiet mode could hide deeper problems that could occur in the future.
