if you could use an evaluation version of SSC Serv [0], please let me
know. The "free edition" is capable of collecting CPU and interface
statistics, the full version collects memory, disk (among others) as
well.

When configuring a *table*, the plugin expects multiple values to be
returned. If you do not specify the "Instance" option, the last part of
the OID will be used as instance, in the hope that this is unique.

If, however, the data is returned as

  hrProcessorLoad.1.0 = 12
  hrProcessorLoad.2.0 = 13

both values will use "0" (the last part of the OID) as instance.

Could you provide an snmpwalk of the entire table? This would make it a
lot easier to tell you how to configure the plugin.

Best regards,
