AWStats is short for Advanced Web Statistics. It´s a free tool that generates advanced web server access statistics graphically. This web server log analyzer works as a CGI or from the command line and shows you all possible information your log contains, in a few graphical web pages. It uses a partial information file to be able to process large log files, often and quickly. It can analyze IIS 5.0+, Apache log files and some other web servers. AWStats is a free software distributed under the GNU GPL.

Requirements:

• Your server must log web access in a log file you can read (better if read and write access).
• You must be able to run perl scripts (.pl files) from command line and/or as CGI. If not, you can solve this by downloading the latest Perl version at ActivePerl (Win32) or Perl.com (Unix/Linux/Other).

Supported OS and Web Servers:

AWStats can work with all web servers able to write log files with a "combined log format" like apache. It can also work with IIS 5.0 or higher (Some users have reported that you can setup your log format as required by AWStats with IIS 4.0 but you need a service pack). Because AWStats is in perl, it can work with all Operating Systems.

Examples of used platforms (reported by AWStats users):

• OS: Windows NT 4.0, Windows 2000, Windows Me, Linux, Macintosh, Solaris, Aix, BeOS, ...
• Web servers: IIS 5.0, Apache, WebStar, IceCast, ...
• Perl interpreters: mod_perl for Apache, ActivePerl 5.6, Perl for unix 5.0, ...
