There isn't enough information there to be sure, but I'll guess that the timestamp of your updates is not on a step boundary (ie an integer multiple of step since unix epoch). If your updates are not exactly on a step boundary, then rrd will normalise the values - it adjusts the figures to fit the fixed 'bins' it has to put the data into. Alex has some excellent descriptions of this on his website : http://www.vandenbogaerdt.nl/rrdtool/ -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson. Novels - poetry - short stories - ideal as Christmas stocking fillers. Some available as e-books. _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
