How to find excessive station in FortiWLM ?

[human01]

Hi, we had an issue on our Wifi last Friday where a station (smartphone) accesses iCloud and uploads data with full bandwidth over an hour. This blocked some internal services others should have used in the same time.

I can see the high traffic (approx 40 Mbps) on the Controller view of the FortiWLM, but how do i get more details?

On which AP does the traffic occure?

Which station is responsible for the high traffic?

Thanks in advance!
