which network IP address and host name a user has logged on

To see the network IP address from which a user has logged on, 
perform the following steps: 
Call transaction OS01, 
Click the "Presentation Server" button, "Change View" button. 
 
If you are using Citrix, you will not be able to view the user individual IP address as it will be the same Citrix IP address.
 
To check the speed and quality of the user's network connection, 
select the desired presentation server and click the "10 X Ping" button.
