The controller probe allows for the server display name to be set as per requirement irrespective of the original hostname.
But this in turn leads to confusion as the probes deployed on server still continue to send data with original hostname.
In order have the data available in DB and in reporting as per name set in controller please perform below changes as well.
Open Controller GUI-->Setup-->Misc.
Under Misc. tab look for 'Quality of Service'
Check mark 'Set QoS Source to robotname instead of computer hostname'
This will in turn set all QoS coming from source as robot name set in robot configuration rather than original hostname.
