Here's an upstart config that Asif put together:

The devmon templates has the OIDs for the most common devices, and even
some uncommon ones.  It's not too difficult to craft up new ones, or extend
existing ones.

Having used both, I think that devmon is easier to get up and running,
unless you have experience with only MRTG.  If all you want is interface
in/out traffic and error rates, MRTG will do what you want.

But you might be surprised by how much devmon gives you out of the box -
once you have it up and running.  I had a situation where a faulty power
supply was detected immediately devmon started looking at it.  Xymon has
special code to handle devmon messages, so the Xymon/devmon integration is
superior to MRTG in many cases.

I'm happy to help if you want to persevere with devmon.
