[mrtg] graphing more than two values with mrtg/rrdtool

[Mersberger, Robert]

maybe this is not the place to ask this but, I need help.
 
I have just installed mrtg, rrdtool and rouers2.cgi on a fedora fc9  and
seem to have all things functioning correctly except for updating the
rrd_data files for the site I am polling.
If I do an ls -al of the rrd_data directory I can watch the date and
time change with each run of my mrtg script.  if I dump one of the rrds
I only seen nulls,
 
Can anyone help me this this?

MRTG only holds two (and always two) variables ('in' and 'out') for a
particular Target.  You can therefore only give two parameters.

 

If you want a graph with more than two variables then take a look at the
Routers2 frontend which allows you to define Userdefined graphs over
multiple Targets, or else user RRDTool directly and write code to
generate a graph as you require.

 

See a demo of Routers2 with a combination graph at

I am trying to create a graph that graphs the cpu for three servers.
It only seems to want to graph the first two number?

Is it possible to graph all three values in one graph?
