After you configure a passive monitor in the Monitor Library, you must add it to the individual devices for which you want to monitor services.

Keep in mind that when you assign a passive monitor to a device, an instance of the monitor is added to the device. Changes that you make to the monitor configuration via the Monitor Library affect all instances of the monitor. For example, if you assign a monitor to four separate devices and then make changes to the monitor from the Monitor Library, all four instances of the monitor adopt the changes.

If you are assigning an passive monitor to a device that uses WMI (Windows) or SNMP credentials, before assigning a passive monitor, make sure that the device has the proper credentials assigned. For more information, see Managing Credentials.
