Terminal Server - Stats of a RDP Connection

Hi,

i am looking for a solution to monitor the stats of a rdp connection. There was a way to show the stats of a running RDP Connection at the Windows 2008R2 (Remotedesktopservice Manager > Users > Right Click a User > Status). But i dont find a way to do the same on a Windows 2012 R2 with a Remote Desktop Gateway. Im looking for the RDP Resolution. Also it would be good if there is a log of previous RDP Sessions, but i think that wont be logged. 

Thanks for your help :)
