[mrtg] Re: Windows 2000 CPU numbering

[Jerry Heidtke]

This happens because Microsoft is incapable of understanding or following
industry standards.

Same thing happens with instances of network interfaces, storage devices,
etc.

If you need to monitor performance items on Windows servers reliably and
consistantly, you cannot rely on any mib that Microsoft has written, or any
standard mib that Microsoft has implemented. If your hardware vendor has
supplied agents with their own mibs, use those. Otherwise use external
scripts to access perfmon or wmi stats. If neither of these are an option,
you're out of luck.

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
