A Fast Web Server Log Analyzer - Visitors

Visitors is a very fast web log analyzer for Linux, Windows, and other Unix-like operating systems. It takes as input a web server log file, and outputs statistics in form of different reports. The design principles are very different compared to other software of the same type:

* Designed to be executed by the command line, output html and text reports. The text report can be used in pipe to less to check web stats from ssh.
 * Support for real time statistics with the Visitors Stream Mode.
 * To specify the log format is not needed at all. Works out of box with apache and most other web servers with a standard log format.
 * It's a portable C program, can be compiled on many different systems.
 * The produced html report doesn't contain images or external CSS, is self-contained, you can send it by email to users.
 * Visitors is free software (and of course, freeware), under the terms of the GPL license.

The simplest usage, to be used interactively when you have a web log to check (for example over ssh in your web server), just type following to produce an human readable output in text only.

To generate html web stats with much more information you may use instead this:

visitors /var/log/apache2/access.log -o html > report.html

If you want information on the usage patterns for your site you must provide the url prefix of your web site, and specify the --trails option.

visitors -A -m 30 access.log -o html --trails --prefix http://yoursite.com > report.html
