cannot see any PID or process id

Hi I want to see CPU, GPU utilization.

I set up host and target.

My computer profile is below
host setup

  • LINUX 14.04 installed
  • Tegra Graphics Debugger for L4T installed


  • Jetson tx2 with pytorch, python program

I make debugger installation. It shows green tick.
I move to Attack tab, but I cannot see any PID OR process id …
You can see below images for my situation.
