finding client's ip address or computer name when monitoring RDP sessions in RDS 2012R2

hello

it is a common need that in our RDSH server 2012 R2, we want to see from which computers are now connected to our session collections

i verified both server manager and powershell Cmdlet such as Get-RDUsersession, but none of them shows from which IP address or computer client's computer name or ip address. both only shows server's IP address.

 i remember that tsadmin.msc in server 2008 had such ability.

any workaround ?

thanks in advanced
