Question is little bit confusing here. Let me rephrase if I get it correctly.
You want to directly connect a system to Qradar console so that you can access the GUI to view log/events?
If I understand it correctly, when you say directly connect a system to QRadar console, that means you are near and around the QRadar physical system. So, why not directly attach a keyboard and monitor to the QRadar server instead?
