steps to get a Mac to report CPU and memory load via SNMP?
Typically, you can use laLoadInt to get processor load, and hrMemorySize and related MIBS to get memory metrics.  However, my experience is that on Mac OS (at least, on 10.8.5), snmpd was compiled without kmem, because apparently apple doesn't support the calls.  I am amazed that Apple would simply remove this feature, but it appears that they decided we could live without it.

Anyway, even on my 10.8.5 system, I can get 1, 5, and 15-minute processor load averages with the OID laLoadInt.&lt;1 2 or 3>
