Hi @jalf2
Well you could either use “check_snmp” with specific OIDs and run this as “classic” check
via a rule, or - if you already have some Nagios plugins and want to get up and running quickly - try
to use existing plugins via MRPE. The latter works quite well, until one has the time to write a “real” plugin (or decides that he/she can live with the existing check and MRPE… 
).
HTH,
