Instead of averaging the known values, calculate the sum. For example, if I have an RRD file w/1-min RRAs and I want to fetch at a 30-minute step (lower resolution across a large time frame), I'd be looking for the sum of each RRA value during each 30 minute interval. -Derek On Tue, Aug 21, 2012 at 9:55 AM, Simon Hobson <li...@thehobsons.co.uk> wrote: > Derek Haynes wrote: > >>For reason (1), the common argument is you can calculate this by >>multiplying the average by the duration of the CDP.
