What aspect of a registered device is NOT displayed in Device Manager?

In Device Manager, the aspect that is not displayed for a registered device is the firmware version. Device Manager focuses primarily on providing real-time data and statistics regarding devices and their operational parameters. This includes visualizing aspects such as the device name, average log rate, and log status, which help administrators monitor performance and logging activities.

The firmware version, however, is typically found in the device's settings or detailed device information sections, but it is not a core performance or status indicator that Device Manager would highlight in its main interface. Therefore, when managing devices within FortiAnalyzer, the firmware version does not appear in the Device Manager's overview, making it an aspect that is indeed omitted from that specific display.
