All stats report the past. You are updating at time "t" saying to RRDtool "from the last moment until now, ``this'' happened" (where ``this'' depends on what you input into what type of counter). This is quite normal when you compare it to network stats: hh:00 counter=100,000 hh:05 counter=103,000 increase in value: 3000 increase in time: 300 rate 3000/300 = 10 per second This update describes the time range hh:00 to hh:05 A GAUGE is just a way of saying to RRDtool: "I already know the rate, don't try and compute it yourself" Hence this rate is also valid for hh:00 to hh:05 when you present it to RRDtool at time hh:05. In order to do what you want: In your *front end* remember the rate/speed/whatever, update with the previous value. This way you tell RRDtool the speed *was* 26.7 in the previous time. Dig into the archives (fairly deep IIRC) for a discussion on modem lines in use. Similar story, similar solution.
