[mrtg] Re: Windows 2000 CPU numbering

[Manny Ortega]

That's one of the problems with windows and dual cpus.
Everytime you reboot the machine, 95% of the time the oids will change.
When that happens and I notice that the graphs for cpu are messed up, I do
an snmpwalk on 1.3.6.1.2.1.25.3.3.1.2.1 and the first two instances are the
cpu instances.
I change those numbers in the config file and restart MRTG.
A pain in the butt but reboots do not happen very often on my dual cpu
machines.
I just implemented a quad Xeon server but I don't think I'll graph cpu usage
because it's not worth it.

Subject: [mrtg] Windows 2000 CPU numbering



Hello,

Is the CPU numbering different on different Windows 2000 dual
processors machines? For example, on first host:

(Iso.org.dod.internet.mgmt.mib-2)
#snmpwalk -OT 1stwindows2000host .1.3.6.1.2.1.25.3.3
[snip]
host.hrDevice.hrProcessorTable.hrProcessorEntry.hrProcessorLoad.1 = 0
host.hrDevice.hrProcessorTable.hrProcessorEntry.hrProcessorLoad.2 = 0

On second host:

#snmpwalk -OT 2ndwindows2000host .1.3.6.1.2.1.25.3.3.1
[snip]
host.hrDevice.hrProcessorTable.hrProcessorEntry.hrProcessorLoad.2 = 0
host.hrDevice.hrProcessorTable.hrProcessorEntry.hrProcessorLoad.3 = 0

Why are the CPU numbered 0,1 on the 1st host and 2,3 on the 2nd host
when both have only 2 processors and are capable of having at most 2
processors?

I am trying to get the load from dual processor Windows boxes and the
above behavior is causing problems because on some boxes I have to
query 0,1 and and some I have to query 2,3. I wish the index started
uniformely at 0...

Thank you
