OpManager monitors the system resources using SNMP by default. However, in the absence of SNMP on the devices, the non-SNMP windows devices can be monitored using WMI. All the Windows device templates have the resource monitors preconfigured. All you will need to do is, disable the SNMP monitors associated and select the WMI monitors and associate them to the required devices.
For monitoring the Windows environment, OpManager must necessarily be installed on a Windows machine. Besides, the device where OpManager is installed and the monitored remote Windows devices must have WMI, RPC, and DCOM services enabled on them. Authentication to the remote devices using WMI requires you to login as a domain user with administrator privileges. This is a requirement of the WMI protocol. If the device is in a workgroup, the system user name and password should suffice.
Steps to configure WMI Monitoring
