After you configure an action in the Action Library, you must add it to the individual devices and monitors for which you want to receive notifications or related tasks performed.
You can assign one or more individual actions to a device, or an instance of an active or passive monitor assigned to a single device.
Note: When you assign an action to a device or monitor, an instance of that action is added to the device or monitor. Changes that you make to the action's configuration via the Action Library affect all instances of that action. For example, if you assign an action to four separate devices and then make changes from the Action Library, all four instances of that action adopt the changes.
