Location of website statistics for apache2
 

I used to know where this is. There's like a folder, somewhere, that has graphs of like browsers and stuff.

I'm using gentoo.

I've never used Gentoo, but just try searching your system for webalizer or awstats.

If you have neither of them, you should be able to download them via Portage.
Once again I'm not familiar with the Portage system, but here's what I found:

http://www.gentoo-portage.com/app-admin/webalizer
http://www.gentoo-portage.com/net-www/awstats


Or you could always try installing them yourself from webalizer.org or awstats.org

Hope that helps :)
