sysUpTime is the uptime of the system.  Useful for dick size wars
and for explaining why a counter has reset to zero or why an UPS
is really needed, and not only for those "important" servers.

As an example: it may look like
system.sysUpTime.0 = Timeticks: (463113884) 53 days, 14:25:38

You already found the nomib2 option so you know how to skip it.

Note that this is just what "4:NOCOMM at 10.0.0.1" translates to. In your
case, you didn't monitor any different from what MRTG does by itself.

This syntax is more useful if you need to graph
<whatever but not being the interface counters you normally would graph>
however this is a bit long :)
