Daily accounting

Hi everyone, I have seen a lot of people who are trying to get traffic accounting collected at regular intervals to generate graphs and view per day/month etc... I have made a few modifications in order to achieve this. You can see it at http://www.netexpertise.eu/en/FreeRadius/DailyAcct.html It works on Mysql setup but can be adapted to any db. I'd be grateful to get some feedback on this. A lot of ISPs are running into this problem. Hope this helps Regards, David
