I liked some of the defaults of the plesk functionality better than the ones provided by the referenced explanation above found at:

If you can follow through the script I adopted, you can make the required changes to the /etc/awstats/awstats.model.conf file. Also, note, I simply downloaded the default package from awstats rather than using the fedora rpm, so you can get it working, for example, from the following package:
http://voxel.dl.sourceforge.net/sourceforge/awstats/awstats-6.3-1.noarch.rpm
The script will be attached as a .txt file as it appears that I'm not allowed to paste it in here for some reason.
