snmpd(8) aka /usr/sbin/snmpd is *not* Net-SNMP. It generally prefers
standard MIBs where possible, the UCD/NetSNMP ones are generally
not used (except that UCD-DISKIO-MIB *is* used, I don't think there
was a good alternative standard MIB for this).
For Memory/CPU use, look in the Host Resources MIB (RFC 2790):
HOST-RESOURCES-MIB::hrStorageTable
HOST-RESOURCES-MIB::hrProcessorTable
Examples:
snmptable -v2c -c public localhost hrStorageTable
snmptable -v2c -c public localhost hrProcessorTable
snmpget -v2c -c public localhost
hrStorage{Descr,AllocationUnits,Size,Used}.{1,2}
snmpwalk -v2c -c public localhost hrProcessorLoad
LibreNMS, for one, can pick these up directly.
(There is also /usr/local/sbin/snmpd / /etc/rc.d/netsnmpd -
this is still needed in some special situations, but snmpd(8)
is more trustworthy).
