If I were you, I would start at http://www.wtcs.org/snmp4tpc/default.htm.
However, if snmputilg.exe is saying that these are valid OID's, you probably
already have the perfmon snmp extension installed. In that case, your
problem is probably lack of an instance number. Try adding a .0 or .1 to the
end of the OID's you are using.
For a quick solution for graphing a single CPU, just use this as a target
line:
Target[CPU0]:
.1.3.6.1.2.1.25.3.3.1.2.1&.1.3.6.1.2.1.25.3.3.1.2.1:community at server
MS's preferred method of remotely monitoring system performance doesn't use
snmp at all.

Jerry thanks for the response,
Unfortunately most of my servers are not Name brand machines. How do I
make my MRTG config file know that it must use the Host Resources MIB
statistics?
The OID's that I used were the ones returned by snmputilg.exe, is it
possible that these are wrong even if they returned correctly?
I have tried the suggested idea's and I still get the same errors. Is
there a help doc (for dummies!) that outlines EXACTLY what I need to
install, start, run, turn off on so on to make this work. I have found
numerous documents, but they all see to start in the middle and I think
that I have missed a step or two in the beginning.

The OID's you are trying to graph aren't supported on a standard W2K
installation. They require the installation of the perfmon snmp
extensions, which isn't supported by Microsoft at all on W2K, and isn't
supported anymore by Microsoft on NT.
If these servers are from a major manufacturer such as Compaq, IBM,
Dell, etc. your best option is to use the hardware management agent
OID's provided by the manufacturer. For example, for a Compaq server
running the Insight Management agents, you could use a target line like:
MaxBytes[_]: 100
WithPeak[_]: ymw
Unscaled[_]: ymwd
Suppress[_]:
Options[_]: growright, gauge, withzeroes, nopercent
YTics[_]: 10
ShortLegend[_]: % CPU
YLegend[_]: Processor Load
LegendI[_]: CPU % 5 Min:
LegendO[_]: CPU % 1 Hr:
Legend1[_]: Processor Load % 5 Min Ave.
Legend2[_]: Processor Load % 1 Hr Ave.
Legend3[_]: Peak Processor Load % 5 Min Ave.
Legend4[_]: Peak Processor Load % 1 Hr Ave.
# CPU util. thru CIM mibcpqHoCpuUtilFiveMin and cpqHoCpuUtilHour # One
target per CPU
Target[CPU0]:
.1.3.6.1.4.1.232.11.2.3.1.1.3.0&.1.3.6.1.4.1.232.11.2.3.1.1.5.0:
Title[CPU0]: Processor Load Statistics for Processor 0 on
PageTop[CPU0]: Load Statistics for Processor 0 on
If using these agents is not an option, then for W2k you could use the
Host Resources MIB statistics. The CPU stat is more limited, giving the
average over the past minute. The OID for the first CPU is
.1.3.6.1.2.1.25.3.3.1.2.1

Subject: [mrtg] CPU utilization graphs
Hello everyone, Happy New Year.
This is my first post so please be gentle!
I have been using MRTG to monitor my WAN traffic for 4 months without
any issues. What a great tool! Now i want to use it to graph CPU and
(eventually) disk access times on my WIN2K servers. I have been reading
as much information as i can find on the web but i always come back to
the same error messages:
WARNING: Skipping Update of localhost.processorload, outlast is not
defined
WARNING: Skipping Update of localhost.processorload, inlast is not

I used a small program called snmputilg.exe to get the relevant OID's,

</TABLE>
For the moment i am trying to get it working on the localhost, but it
fails the same way on other servers. SNMP is running in all cases.
Please help, i have been banging my head on this for a week.
