I definitely want to graph more than two variables, I will try routers2.

Thank you so much

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?
