W3Perl is a free logfile analyzer 

W3Perl is a monitoring tool for Web/FTP/Squid or mail servers.
The perl scripts analyze logfiles and produce HTML/PDF reports (which can be sent by email).
It can use server's logfiles or a javascript tag to be inserted in web page (web analytic)
W3Perl can be run from the command line or from the web interface.
