[mrtg] Linux CPU Usage

[Joey Officer]

heres an intersting one I found I had a problem with today.

I'm using CMU's package of SNMPd of Linux, ver3.7.  I've compiled the MIB
tree so that I can read and parse through to find the OID needed for CPU
utilization, I found it.  When I use a browser, I am able to get the correct
results from the SNMP oid.  However when I do an snmpget I get the following
error:

[harryk at prepaid harryk]$ snmpget 192.168.10.200 public
.1.3.6.1.4.1.1575.1.5.2.3
Error in packet.
Reason: There is no such variable name in this MIB.
This name doesn't exist:
enterprises.tubs.ibr.linuxMIB.linuxObjects.linuxLoadAvg1

When I add a ending zero, I'm able to get the proper data from the command
line:
[harryk at prepaid run]$ snmpget 192.168.10.200 public
.1.3.6.1.4.1.1575.1.5.2.3.0
enterprises.tubs.ibr.linuxMIB.linuxObjects.linuxLoadAvg1.0 = INTEGER: 116

But I am still unable to get the proper information into MRTG.  Its like its
ignoring the data.  Also see attached a copy of my conifg...

Can anyone offer any suggestions.
