Monitoring Resources Using WMI

OpManager monitors the system resources using SNMP by default. However, you can also monitor Windows-based devices using WMI, and both types of monitors can used to fetch metrics specific to that protocol. All the Windows device templates have the resource monitors preconfigured. All you will need to do is 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

  1. Navigate to Inventory -> Devices and then click on a device to open its snapshot page.
  2. Go to the Device Snapshot page.
  3. Select Monitors → Performance Monitors, and click the Actions button on the top-right corner of the page.
  4. 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.
  5. Click Add at the bottom of the page. The selected WMI-based monitors will then be associated to the device.

Note: Check that the configured WMI credential of the device passes the NS-lookup and reverse lookup, in order to ensure data collection happens without any issues for that device.
