CPU Utilisation OID

IG — Tue, 16 Sep 2025 13:16:05 GMT

Hello. I am trying to monitor our VSP devices with Zabbix and the Extreme Template (EXOS) does not fully translate over 100% on all OID's. I have managed to work out all the other OIDs that were incorrect, but the last one I am stuck on is CPU utilisation %

I have tried 1.3.6.1.4.1.2272.1.85.10.1.1.2 (rcKhiSlotCpuCurrentUtil) but this is not working. Does anybody know which OID I can use?

They are VSP 7400's running VOSS 8.3.1.0

Thanks

Hi,

You have mentioned using the EXOS template, and then using the VOSS operating system. They are quite different things from what was once different manufacturers.

I didn't set this up, but one of ours we are using:

Average CPU utilisation (1 minute): 1.3.6.1.4.1.2272.1.1.1.1.1.6

Average CPU utilisation (5 minutes): 1.3.6.1.4.1.2272.1.1.1.1.1.7

Average CPU utilisation (15 minutes): 1.3.6.1.4.1.2272.1.1.1.1.1.8

You've correctly identified the problem: the standard EXOS templates are not compatible with VSP devices because they run a different operating system, VOSS (Virtual Operating System), and use a different set of MIBs. The OID you attempted belongs to a different vendor (`2272` is a KHI Systems OID).

For Extreme VSP devices running VOSS, the most commonly used OID for global CPU utilization is:

**1.3.6.1.4.1.1916.1.32.1.1.1.3.0**

This OID corresponds to `s5GlbMonCpuUtil.0` within the **Extreme-VOSS-S5-GLOBAL-MONITORING-MIB**. This OID will provide the overall CPU utilization percentage for the device.

If you are looking for per-slot or per-module CPU utilization, you may need to use a different OID from the `Extreme-VOSS-ENTITY-MIB`, which often has a table of values indexed by slot number. However, the first OID is the most direct solution for overall device CPU monitoring.

I recommend trying this OID and running a simple `snmpwalk` or `snmpget` command from your Zabbix server to the VSP device to confirm that it returns a value before adding it to your template.

Thanks both for your responses.

I am aware that EXOS and VOSS are very different, but in Zabbix there is no default Template for VOSS devices. So I used the EXOS template which was able to cover many things such as network interface discovery and metrics.

However, there were a few items that unfortunately did not translate over fully. These being CPU utilisation, memory utilisation, Fan & PSU discovery.

For anyone that finds this post who is using Zabbix with the same issue as myself I was able to get this working with the following:

CPU Utilisation: 1.3.6.1.4.1.2272.1.85.10.1.1.2.1
Memory Utilisation: 1.3.6.1.4.1.2272.1.85.10.1.1.8.1
PSU Discovery: 1.3.6.1.4.1.2272.1.4.8.1.1.1
Fan Discovery: 1.3.6.1.4.1.2272.1.101.1.1.4.1.3
