Description:

W3Perl is a free web logfile analyzer which is also able to parse FTP
and Mail logfiles.

It is one of the most powerful package as it includes advanced stats
like real-time, sessions, URL mapping, virus, along with classical
stats like hosts, pages, traffic, countries, agents, referers, errors,
filetypes, robots, search engines and much more.

It supports most logfile formats, including Apache (CLF, ECLF, NECLF)
or IIS (W3C, Microsoft or any variation). Logs can be daily or monthly
split and/or compressed.

A web administration tool allows you to manage your configuration
files to customize your stats output. A demo is available at
