[mrtg] mac os mibs

[Greg Donald]

I'm on Mac OS 10.4.  I'm trying to find the correct mib to use for cpu usage:

> snmpwalk -v 1 -c public localhost | grep -i cpu

turns up nothing and everything else I've tried:

> snmpwalk -v 1 -c public localhost | grep -i proc

SNMPv2-MIB::sysORDescr.4 = STRING: The MIB for Message Processing and
Dispatching.
HOST-RESOURCES-MIB::hrSystemMaxProcesses.0 = INTEGER: 532
HOST-RESOURCES-MIB::hrDeviceType.768 = OID:
HOST-RESOURCES-TYPES::hrDeviceProcessor
HOST-RESOURCES-MIB::hrDeviceType.3072 = OID:
HOST-RESOURCES-TYPES::hrDeviceCoprocessor
HOST-RESOURCES-MIB::hrDeviceDescr.3072 = STRING: Guessing that there's
a floating point co-processor
HOST-RESOURCES-MIB::hrProcessorFrwID.768 = OID: SNMPv2-SMI::zeroDotZero

results in errors like this:

> /opt/local/bin/mrtg /etc/mrtg/cpu.cfg

Unknown SNMP var hrDeviceDescr.3072
 at /opt/local/bin/mrtg line 2149

My cpu.cfg currently looks like this:

> cat /etc/mrtg/cpu.cfg

WorkDir: /opt/local/apache2/htdocs/mrtg
LoadMIBs: /usr/share/snmp/mibs/UCD-SNMP-MIB.txt

Legend2[localhost.cpu]:

I've tried a number of different Target entries after reading mailing
list archives and Google'ng.

Is there a special mib file for Mac hardware?  I didn't see anything
in /usr/share/snmp/mibs that was Mac specific.  Or is there a special
Mac how-to somewhere Google doesn't know about?

My traffic graphs looks great, but I also want CPU, memory, and load  :(


Thanks up front,
