No, RRDTool only ever stores rates, not values. With a counter data type, it stores the previous counter value only so that it can calculate the rate. Each time you do an update, it works out the difference (new counter value minus old counter value) and then divides it by the time since the last update to get a rate. So if you fed it the values 60 and 90, two minutes apart, the difference would be 30, and divided by 120 seconds, the rate stores would be 0.25. The rates calculated are then normalised to fit your step period. Alex has an excellent tutorial on this at http://www.vandenbogaerdt.nl/rrdtool/ >3.

If anyone knows where I might get hold of one I'd be grateful - requests to Canon drew a blank, it's been out of support for years. Alternatively, if anyone has one of these and would let me image their hard disk ... Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
