After System Center 2012 – Operations Manager has discovered and is monitoring a network device, you might want to stop monitoring the device because it is being replaced or because there is no business value in monitoring that particular device or for any other reason. To stop monitoring a device, you can use maintenance mode or you can delete the network device from the discovery rule. You can also restore a deleted device that was discovered by a recursive discovery rule.

To delete a device that is the starting point for recursive discovery, you must first delete the discovery rule or remove the device from the discovery rule.

Note

You can identify the discovery rule associated with a discovered network device by right-clicking the device in Network Devices or Network Devices Pending Management and then clicking Discovery Rule Properties.

If you delete a device that was discovered by a recursive discovery rule, it will be added to the exclude list of the rule. If you want to have that device discovered and monitored again, you must remove the device from the Exclude Filters page of the rule’s properties and run the discovery again.

To delete a network device discovered by explicit discovery

  1. In the Operations console, select the Administration workspace.

  2. Click Network Devices, right-click the device that you want to delete, and then click Delete.

    Note

    You can select multiple devices to delete.
