I have an SNMPget statment that I am trying to plug into Nagios to monitor the CPU I/O Wait Time on several Debian /Xen Host servers. They are Net-SNMP compliant.

If i run the snmpget querie it returns the following:

UCD-SNMP-MIB::ssCpuRawWait.0 = Counter32: 484856

How do I interpret this data? What is Counter32? Is there a better way to build the snmpget querie that will output meaningful data? (I am sure the above is meaningful to something/somebody, but I don't have a clue...)

Thanks in advance
