Thanks, > Sure, very easy. Usually you will have a tool to collect data in some rrd files. Then you generate graphs with some "DEF"-commands definig data sources like this:
DEF:load=/usr/local/rrdtool/system.rrd:load:AVERAGE \ DEF:hda2=/usr/local/rrdtool/system.rrd:hda2:AVERAGE \ DEF:hdb3=/usr/local/rrdtool/system.rrd:hdb3:AVERAGE \ ... and so on. The command "DEF:shoesize=/where/is/my/rrd/file:mike:AVERAGE lets rrdtool collect the average values from the value "mike" out of the file /where/is/my/rrd/file to be available with the name "shoesize" and to be displayed in a graph with the command: LINE1:shoesize#00bb00:"Mike's shoesize" \ And you may define multiple DEF-commands each extracting values out of different rrd-files just by naming the files.
