routers: graph for bandwidth??

Hi all, I finally got my system configured for all of the different servers I have, including the cisco firewall and switches (thanks to help from here in the mailling list).

But I stumbled upon something I can't seem to figure out, and searching doesn't give me the answer I'm looking for (wrong search strings?)

Quite simply put, I want to have a graph of all the bandwidth that's being used for a router. Is this possible (I know it is with a mrtg addon that I saw somewhere), with DEVMON?

Is there any examples anywhere?

Thanks!

William
