So use derive data type, write 0.5 (or any larger value that's accumulated) followed by 0 whenever the counter tips over ? Guess we need to write 0 periodically to avoid getting long periods of unknown. So we end up with : forever read value if value > min reset counter reset timer write T:value to rrd writeT+1:0 to rrd else if timer > some_period write T:0 to rrd reset timer sleep for a bit go back and do it all again _______________________________________________ rrd-users mailing list rrd-users@lists.oetiker.ch https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
