Jtop is a Jetson-specific system monitoring tool that allows real-time viewing of CPU/GPU usage, memory, power consumption, temperature, NVPModel, power mode, fans, process information, like htop. It helps you to quickly diagnose bottlenecks, monitor resource consumption in modelling, and is one of the most common debugging tools that Jetson has developed.
Step1. Install Jtop
Enter the following command in the jetson terminal.
sudo apt update
sudo apt-get install python3-pip -y
sudo -H pip install -U jetson_statsThe first installation of Jtop requires restarting the device to start Jtop's system service.
sudo rebootStep2. Start maximum power and Jefferson clock
# Enable Jetson MAXN SUPER mode
sudo nvpmodel -m 2
# Enable Jetson clocks so the CPU and GPU run at their maximum frequency
sudo jetson_clocks
# Open `jtop` to inspect system resources

In Jtop, you can switch information from different pages by number 1, 2, 3...
Page 2 here monitors the use of GPU and the process uses GPU.

Page 4 Memory Management
You can increase the exchange area by s,b,+,-button

Page 6 Control Page to allow you to adjust the hardware running mode, heat-dissemination policy and clock frequency of Jetson Orin Nano
Page 7 allows access to Jetpack, various environmental components and system information such as web IP
Finally, press the q on the keyboard to exit jtop.
