The devices view gives you an overview of the devices from all linked Intune tenants
The filters on the left hand side can be used to filter in/out devices, for example, to see only non-compliant devices in the New York office. You can also use the Search box in the top left corner of the filter bar to search for any property that is not a date/time stamp, even if not visible. For example, if you search “iOS” you will see all devices with an OS type of iOS, even though this property isn’t visible as a column in the table
The columns to the far right of the view show you the state of device config, compliance, managed apps and OS patch
