Every 5 minutes we get an exact count of number of messages received in the last 5 minutes. qmailmrtg7 multiplies that value by 12 to change the time scale to msg/hour. That value is handed to mrtg which averages it with the prior data samples. > I know it's doing the messages.. but how do you do > msg/hour in a 5 minute average? messages(in 5 minutes) * 12 = msg/hour > I guess I'm missing some sort of logic there.. Most folks find it easier to view msg/hour instead of msg/5 mins. Hence the multplication. Which means, if you only get 1 message in 5 minutes, mrtg will show 12msg/hour. Ken Jones
