RE: [WhatsUp Forum] CPU monitoring on NT systems

Title: Message

Thanks Gareth,

 

Also, please keep in mind when monitoring microsoft machines:

CPU NT: 1.3.6.1.4.1.311.1.1.3.1.1.23.9.0

CPU 2K: 1.3.6.1.2.1.25.3.3.1.2.$INSTANCE

 

The NT implementation is in the enterprise MIB and is an average of all CPUs.  Also, it provides the value at that split second.  So if coincidently a resource intensive process is run every time the MIB is polled via WUG/Denika, the value may be at 90% or greater.  Thus, you would get alarmed depending on the threshold you set.

 

The Windows 2K implementation is in MIB 2 and I believe it is an average over so many minutes/seconds.  So, you don't see the spiking issues that we did in NT.

 

The Microsoft SNMP agent that comes Denika will auto determine if it is being installed on a NT or 2K machine and install the correct MIBs (THEY ARE FREE).

 

Have fun.

 

Sincerely,

Michael Patterson

You need to install the perfmon SNMP agent to publish the performance monitor statistics to SNMP. this is available from the NT4 resource kit, or various sources on the web, e.g. http://www.somix.com/ http://www.wtcs.org/snmp4tpc/

 

Assuming you want to graph usage, you may want to look at something like MRTG http://www.mrtg.org/  or Denika or WebNM both from Somix http://www.somix.com

In order to monitor the CPU usage on a specific NT system, what needs to be done on the NT system itself?  I'm assuming this needs to be done via SNMP.  If so, other than having the SNMP Service installed on the NT system, what else is involved?
