Device groups are displayed in Device Manager > Device & Groups. All devices added to FortiAnalyzer are included in a default device group. You can create custom device groups as well to organize devices for convenient selection in other features of FortiAnalyzer.
Type in the Search field to search for device groups by name. Click to sort the list of device groups in ascending or descending alphabetical order. The default device group will always remain at the top of the list. Select the device group to display its list of devices in the Device Manager pane.
The maximum number of device groups that can be created is the same as the maximum number of devices/VDOMs supported for your VM license or model. See the FortiAnalyzer data sheet on https://www.fortinet.com/ for information about the maximum number of supported devices/VDOMs for your VM license or device.
