The Webalizer


The Webalizer is a fast, free web server log file analysis program. It produces highly detailed, easily configurable usage reports in HTML format, for easy 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.

Tell me more!

  • Is written in C to be extremely fast and highly portable. On a 200Mhz pentium machine, over 10,000 records can be processed in one second, with a 40 Megabyte file taking roughly 15 seconds (over 150,000 records).

  • Supports standard Common Logfile Format server logs. In addition, several variations of the Extended Logfile Format are supported, allowing statistics to be generated for referring sites and browser types as well.

  • Generated reports can be configured from the command line, or by use of one or more configuration files. Detailed information on configuration options can be found in the README file, supplied with all distributions.

  • Supports multiple languages. Currently, English, Spanish, French, German, Italian, Dutch, Russian, Polish, Slovak, Swedish, Catalan and Portuguese (including Brazilian) language files are available.

  • Unlimited log file sizes and partial logs are supported, allowing logs to be rotated as often as needed, and eliminating the need to keep huge monthly files on the system.

  • Distributed under the GNU General Public License, complete source code is available, as well as binary distributions for some of the more popular platforms. Please read the Copyright notices for additional information.
