MAC OS X and SNMP

MAC OS X and SNMP

Is anyone out there using OpManager to monitor a MAC OSX server? I was able to get it conencted via SNMP using Net-snmp as the Vendor, Catagory Server and Type is Linux and the server does show up with the Blue Star but I cannot get any info out of it.
 
I am looking for CPU, Memory and Disk Space Usage.
 
Can anyone help?
 
Thank,

Frank
