I suggest moving the domain specific configuration files into a new directory like /etc/awstats/ispconfig or somewhere else. This directory should be created by the awstats plugin on installation or first use.
The Ubuntu 8.04 LTS distribution contains a script:
It can be configured (see the beginning of this file) to update the statistics for all the ISPConfig managed domains then.
Related topic, both for Webalizer and AWStats: We can enable GeoIP for them if we install the geoip-bin package and take care of downloading the free GeoIP Country database from MaxMind. I haven't tested this yet, however.
