Refer to my previous post (about statistics Api, sdk etc..) i would like to know if there if is possible to make plesk send me a report, on an Excel file or Db file or a CSV file, each month, with detail of Traffic effective used and limit for each domain (with detail on Customer that have the domain). this way i can calculate the treffic exceeded and send to each customer a bill with the cost of exceeded traffic. Is it an integrate function of Plesk o i've to develop it? in this case, what you suggest to me, how i can start (i can develop in VB.NET and ASP.NET - no c++ or php )? PS. Can Plesk automatically lock the domain wich reach Traffic Limits?? if yes, what error page is sent to the visitors? How the customer can unlock the domain by his-self (buyng extra-traffic on-line without the intervent of the Admin)?? Sorry for my english Byes!
