Hi Rob, looks like like you simply forgot to print out the graph.
Try this: rrdtool graph brisqck.gif DEF:mybrisqck=brisqck.rrd:brisqck:AVERAGE \ LINE2:mybrisqck#FF0000:"Printer" In your command you specified a Datasource but didn't printed anything out. See the rrdtool graph help on www.rrdtool.org kind regards -- Falko Zurell - Webmaster Pixelpark AG http://www.pixelpark.com Rotherstraße 8 10245 Berlin .

About a year ago I used MRTG to perform this task, but I now require the extra graphical functions of RRD.
