Monitoring Resources Using WMI

 

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.

 

 

Prerequisites

 

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

 

Go to the device snapshot page.

  1. From Monitors --> Performance Monitors section, remove the SNMP-based monitors if any.
  2. Click Add Monitors link on the right bottom.
  3. Now, from the list of resource monitors, select the CPU, Memory, and Disk Utilization monitors which has the protocol name as WMI against the monitor name.
  4. Click OK. The monitors are added in the template under the Monitors column.
  5. Click Apply. All the Windows devices to which the monitors are associated are listed. Another column also displays devices which are classified as 'Unknown'. You can pull the required devices from this list too. Click Apply once again.

The WMI-based monitors are associated to the device.
