Here's what your Manager dashboard should look like if you've connected a lot of ADC's to it.
If you want to know more about a particular subject, click on the corresponding widget. We'll look at Devices Health.
In the dashboard view, you see only three options, Offline, Online, Unmanaged. At first view, it will tell you only the rough proportion of which devices are offline/online/unmanaged.
But if you hover your cursor over it, it will give you the specific number of, say, offline devices.
If you want to know more, however, if you want to see all the information, click on the widget and it will bring you to Device Management
