Logfiles 

W3Perl can parse crunched and/or split logfiles. It can be read logfiles from load-balancing server.
Remote logfiles can be retrieve before running the stats using rsync/sftp or wget.
If you don't have access to logfiles, W3Perl can be used with javascript tag. Adding a small piece of javascript in the web pages you want to monitor and the script will create the logfiles for you.

- Page Tagging

Insert a small piece of javascript in your pages and logfiles will be created that you could then analyze with W3Perl. Logfile format is ECLF so referer and agent are available. Files are daily split.

- Counter

Get stats about your external links. Replace your href link with a php script which will create a logfile you could later analyze with W3Perl.
