Console Command to Turn this GUI off?

A while ago a friend was playing on my Gmod and used a console command to bring up the GUI pictured in the screenshot. It ended up staying and I got used to it. After a while it began to get annoying and obstruct other GUI. I asked my friend what command he used but he didn’t remember.

Anyway, does anyone know how to turn it off? It’s the thing with fps, ping, etc.
