Well, there are over 10,000 snmp private OIDs on an average Cisco router,
and probably another 10,000 standard OIDs.  So, there are at least 20,000
things you can monitor on a Cisco router out of the box.  Most of them would
be fairly uninteresting graph wise, but I'm sure if read through all of the
mibs you would find something interesting...

I use MRTG to monitor cisco routers for:
interface traffic
DLCI traffic
specific traffic patterns
VOIP off hook time
successful pings (with thresholds to page me when a router is down)
CPU utilization

number of fish that have swum past a dam
number of people who have run a red light on a particular intersection

In other words, MRTG can be used to graph any time-progressive data that you
can enumerate.  The problem is, of course, figuring out how to enumerate the
