[mrtg] Monitoring windows

[Jeff Mills]

Hi all,
I have been using mrtg for a while now to monitor cisco routers and mailscanner, and its been working great.
I would now like to start monitoring our Windows servers, but have run into a problem.

I've used "GetIf" to browse the mib tree on the windows box to get the identifiers.
For instance, .1.3.6.1.2.1.25.3.3.1.2 is for processor load.
.iso.org.dod.internet.mgmt.mib-2.host.hrDevice.hrProcessorTable.hrProcessorEntry.hrProcessorLoad

If I snmpwalk this, it appears to be correct:
snmpwalk -v 1 -Of -c public pocl-jet 1.3.6.1.2.1.25.3.3.1.2
.iso.org.dod.internet.mgmt.mib-2.host.hrDevice.hrProcessorTable.hrProcessorEntry.hrProcessorLoad.3 = INTEGER: 5

snmptranslate -Of 1.3.6.1.2.1.25.3.3.1.2
.iso.org.dod.internet.mgmt.mib-2.host.hrDevice.hrProcessorTable.hrProcessorEntry.hrProcessorLoad

However,
when I attempt to use this in mrtg, I get an error.
Here is what I'm using in my config:
Target[cpu_pocl-jet]: 1.3.6.1.2.1.25.3.3.1.2.3:public at pocl-jet:
AbsMax[cpu_pocl-jet]: 100
MaxBytes[cpu_pocl-jet]: 100
Title[cpu_pocl-jet]: Avg CPU Usage in pocl-jet
Legend1[cpu_pocl-jet]: Avg CPU Usage
Legend2[cpu_pocl-jet]: Avg CPU Usage
LegendI[cpu_pocl-jet]: Avg CPU Usage: 
LegendO[cpu_pocl-jet]: Avg CPU Usage: 
Ylegend[cpu_pocl-jet]: CPU Usage
ShortLegend[cpu_pocl-jet]: %
#Options[cpu_pocl-jet]: gauge,absolute,integer,nopercent
PageTop[cpu_pocl-jet]: <H1>Avg CPU Usage in pocl-jet</H1>

And here is what mrtg says:
mrtg /etc/mrtg/mrtg-servers.cfg
SNMP Error:

Firstly, where is "(OID: 1.3.6.1.2.1.2.2.1.10.3)" coming from? Is this what it is trying to look up on the server?
It would explain why mrtg finds nothing, but if thats the case, why is it looking there instead of the target I specify?
Any help is appreciated!

Regards,
Jeff
