[mrtg] can't figure out CPU

[Brian Neu]

Gracious and patient mrtg users:

   A humble mrtg newbie requests your assistance.

    In trying to get MRTG to monitor CPU/system info from the localhost, I have running into the following situation.



So with either v1 or v2c, I get this:

]# snmpwalk -v 2c -c <mycom> localhost ssCpuUser.0
UCD-SNMP-MIB::ssCpuUser.0 = INTEGER: 0

Working,right?  Not for mrtg, at least not the way that I'm trying to do it:

---------   /etc/mrtg/cpu.cfg  -------
WorkDir: /var/www/mrtg
LoadMIBs: /usr/share/snmp/mibs/UCD-SNMP-MIB.txt,/usr/share/snmp/mibs/TCP-MIB.txt
Target[localhost.cpu]:ssCpuRawUser.0&ssCpuRawUser.0:aonetworks at localhost + ssCpuRawSystem.0&ssCpuRawSystem.0:aonetworks at localhost + ssCpuRawNice.0&ssCpuRawNice.0:aonetworks at localhost
----- truncated for your viewing pleasure ----


]# LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/cpu.cfg 
Unknown SNMP var ssCpuRawUser.0

Unknown SNMP var ssCpuRawSystem.0

Soooo, what am I doing wrong?
