Using FortiManager to manage FortiAnalyzer devices
You can add FortiAnalyzer devices to FortiManager and manage them. When you add a FortiAnalyzer device to FortiManager, FortiManager automatically enables FortiAnalyzer features. FortiAnalyzer and FortiManager must be running the same OS version, at least 5.6 or later.
In the Device Manager pane, a message informs you the device is managed by FortiManager and all changes should be performed on FortiManager to avoid conflict. The top right of this pane displays a lock icon. If ADOMs are enabled, the System Settings > All ADOMs pane displays a lock icon beside the ADOM managed by FortiManager.
Logs are stored on the FortiAnalyzer device, not the FortiManager device. You configure log storage settings on the FortiAnalyzer device; you cannot change log storage settings using FortiManager.
For more information, see Adding FortiAnalyzer devices in the FortiManager Administration Guide.
