After about 30 second's of thinking about how to get rrdtool or mrgt to display what Code Red is up to on my server I decided to use webalizer instead. It defiantly gives you a better view on what is going on, have a look at http://203.97.86.130/codered/usage_200108.html . I have put the script in the cron.hourly directory so check back as often as you like.
