For all the dedicated servers that I release, I install (among many others) Apache+PHP, MySQL, phpMyAdmin, and awstats.

AWStats is a bit difficult to install if you are not familiar with it. On top of that, it is very easy to lose data due to mismanagement of server logs. Apache 1.3.x (which I would highly recommend over Apache 2.0.x) has issues with writing to logs larger than 2G, so your site will pretty much just stop responding at this point. I have created a package with AWStats that rotates the logs daily, keeping a 30 day archive, but runs awstats before the archive process - thus, getting your stats, preserving the logs (this information is VERY valueable), and getting around Apache's 2G limitation is not a problem.

If you totally skipped that part because it might be too techie, no worries. Bottom line, for a fast and free solution that gives you loads of information, I beleive that AWStats is a real winner - http://awstats.sourceforge.net for more information.

Please feel free to contact me off list for assistance.

Thanks!
