Description:

AWStats (Advanced Web Statistics) is a free powerful and featureful
tool that generates advanced web (but also ftp or mail) server
statistics, graphically.

This log analyzer works as a CGI or from command line and shows you
all possible information your log contains, in few graphical web pages
like visits, unique vistors, authenticated users, pages,
domains/countries, OS busiest times, robot visits, type of files,
search engines,keywords and keyphrases used, visits duration, cluster
balancing, HTTP errors and also screen size, web browser
java,flash,etc support and more... Statistics can be updated from a
browser or your scheduler. AWStats uses a partial information file to
be able to process large log files, often and quickly.

It can analyze log files from IIS (W3C log format), Apache log files
(NCSA combined/XLF/ELF log format or common/CLF log format), WebStar
and most of all web, proxy, wap, streaming servers (and ftp servers or
mail logs). The program also supports virtual servers, plugins and a
lot of features.
