FortiAnalyzer includes default ADOMs for specific types of devices. When you add one or more of these devices to the FortiAnalyzer, the devices are automatically added to the appropriate ADOM, and the ADOM becomes selectable. When a default ADOM contains no devices, the ADOM is not selectable.
For example, when you add a FortiClient EMS device to the FortiAnalyzer, the FortiClient EMS device is automatically added to the default FortiClient ADOM. After the FortiClient ADOM contains a FortiClient EMS device, the FortiClient ADOM is selectable when you log into FortiAnalyzer or when you switch between ADOMs.
You can view all of the ADOMs, including default ADOMs without devices, on the System Settings > All ADOMs pane.
When ADOMs are enabled, the default root ADOM type is Fabric. Fabric ADOMs show combined results from all Security Fabric devices in the Device Manager, Log View, SOC, Incidents & Events and Reports panes. For more information on Fabric ADOMs, see Creating a Security Fabric ADOM.
In FortiAnalyzer 6.2.0 and earlier, the root ADOM is a FortiGate ADOM. When upgrading to FortiAnalyzer 6.2.1 and later, the root ADOM type will not be changed to Fabric. Resetting the FortiAnalyzer settings through a factory reset will cause the root ADOM to become a Fabric ADOM.
