Just like the consumer Insight, Netgear Insight Pro does magically "sum-up" data ingress and egress on ports, wireless radios, .. This is requied to be split in ingress and egress (to the device, from the device). What is named "Data Consumption" on the Summary widget title, "Data Usage" on the widget graph time line, does become "Traffic Usage" e.g. on the switch ports - here the example not split to ingress and egress, and no units:
And in many locations, just a plain number is shown without any indications of units.
