My test on using unknaszero show a value of 0.0000000000e+000 being stored in the *.rrd > Also, I want to graph the sum of multiple interfaces using the summing > capability of MRTG, but when one of the interfaces is down ( or doesn't > return data ) the porcess stops. The way that we graph the sum of multiple interfaces is by using the 'graph' function of RRDTool. Here as an example of what we do (ex. using 3 interfaces): c:\mrtg\rrdtool\bin\rrdtool graph aggregate.png --imgformat PNG --width 650 --height 150 DEF:onex=64.39.30.21_23.rrd:ds0:AVERAGE DEF:oney=64.39.30.21_23.rrd:ds1:AVERAGE DEF:twox=64.39.30.21_24.rrd:ds0:AVERAGE DEF:twoy=64.39.30.21_24.rrd:ds1:AVERAGE DEF:threex=64.39.30.21_25.rrd:ds0:AVERAGE DEF:threey=64.39.30.21_25.rrd:ds1:AVERAGE CDEF:myxx=onex,twox,threex,+,+,8,* CDEF:myyy=oney,twoy,threey,+,+,8,* CDEF:myzz=myxx,myyy,+ AREA:myxx#00ff00:"Incoming Traffic (AVERAGE)" LINE1:myyy#0000ff:"Outgoing Traffic (AVERAGE)" LINE2:myzz#ff0000:"Total traffic (in+out)" You might want to look at RRDTool's documentation on 'graph' and 'create' for an explanation. We use them in a web page where the user can select the interface(s) that they want to see an aggregate graph of.
