1.) In the Authoring pane, expand Authoring, expand Management Pack Objects, and then click Monitors.
8.) On the Second SNMP Probe for Object Identifier Properties we are going to use the same thing (1 minute Load) “.18.104.22.168.4.1.2021.10.1.3.1” then select next.
9.) On the Build Second Expression for Parameter Name use the same as the first “/DataItem/SnmpVarBinds/SnmpVarBind/Value” for Operator use “Less than or Equal to” and then choose a CPU value that you want to alert on. I choose “1” again for demonstration purposes. Click Next
10.) On the Configure Health Page Change the First Event Raised to Critical

11.) On the Configure Alerts click Generate alerts for the monitor
12.) For testing I downloaded a tool called Manage Engine OpUtils 4 http://manageengine.adventnet.com/products/oputils/index.html I think any SNMP Walker tool will do. What I wanted to do I query the current Value of the CPU (or OID for CPU)

13.) Currently there are no active alerts on the console.
Now I went to my ESX box and create some activity. A “vm-support” from an ssh session will create enough CPU activity.
14.) A SNMP walk on the object shows the value above 1
