In CDM source name is computed as follows:
- From controller’s Robot environment(Status tab of Controller->Robot environment) , value of NIM_QOS_SOURCE is picked. (This value is enabled when in Setup->Misc->Quality of service->Set QoS source to robot name instead of computer hostname is checked).
- If the value is not available, then FQDN is picked
- If set source name is set then, only hostname is taken(remaining is truncated).
You need to restart the robot after making the changes
