I have a table that comtains all of the information form the IIS logs in w3c format. This includes date, time, use ip, page and status. I'd like to be able to calculate the number of visitors my site gets. Basically the definition of a visitor is if a request from an IP comes after 30 minutes from the last request from the same IP, it is considered a different visitor.
As I said My table has date, time and IP address so it should be pretty simple to figure out, I just cant figure out how to do it in Qlikview. Any assistance would be greatly appriciated.
