We are having some problems with log rotation on our Centos box.
So I've edited the daily cron jobs for webalizer and awstats. UPDATE-1 It turns out "psa/admin/sbin/statistics" is updating access_log.processed.
If your statistics package is still not updating, you can either manually refresh the package, or set it to be automatically updated on a regular basis.
The Webalizer is a fast, free web server log file analysis program.
Statistics service is typically set to run once every 24 hours.
If you do not see a change to this page in the next 24 hours contact your server administrator for assistance.
