Monitoring Cisco Routers errors?

For the type of devices I'm looking to monitor(cisco routers, w/ gig & fast e) there should be NO errors. If there's a value other than 0 we've got problems... :) 
  Output queue 0/40, 0 drops; input queue 0/75, 0 drops

Ok, not the hardest part, I was looing for something that would be able to walk the oid tree/interfaces looking for errors. I've got a lot of interfaces on lots of routers, make a specific check_snmp request for each oid is a lot of work.. :)

look for the transport mibs for specific line type (DS1/E1, DS3/E3, SONET, 
etc)
