If you're going through all this trouble, you might as well measure some
interface statistics such as:

- CRC errors, these are an important clue indicating lower layer problems
- collisions, if you use any non-switched ethernet (or even if it's
switched: duplex mismatch is a bad thing and it happens)
- over- and underruns, these indicate (transient) high CPU loads
- input/output drops, to see if you are experiencing congestion

And:

- router CPU load

These should all be easy to measure with MRTG if you can find out how to
read the info from the box using SNMP.
