Now this is a tricky idea.

The "proper way" is to re-write the frontend so it sucks in the graphs
from both. But if you want to keep it within JFFNMS you will have to
work out a way of nailing up the interface numbers. Also there will be
some meta-data you will need to fill in.

The interface will have a RRDTool value, and no poller. You'd create the
interface manually and then note the ID.

The RRD file would need to be then named with the interface ID and a
number, probably 0, eg  interface-1234-0.rrd
The DS is called data.

Then make a graph that uses that file.

You just have to be sure you match the IDs right correctly. Also make
sure the permissions are right as well.  It's a lot of fiddling around,
but I'm pretty sure you know it would be anyhow.
