jtop-light

Lightweight system monitor for the Nvidia Jetson platform

Motivation

I use the excellent jetson_stats to monitor and control my Nvidia Jetson devices.

For some use-cases, this project is a bit too heavy-weight, and has too much overhead and installation hassles. I wanted a very light-weight no-frills system monitor with as less overhead and as easy to install as possible. That meant to rewrite the basic functionality of the jtop tool using C.

Building and installing

Prerequisites:

• build-essential
• libncurses-dev

To build, just type make
To install, copy the resulting binary jltop to a location like
sudo cp jltop /usr/local/bin/
To be able to get all system information, especially the power meters, when running as normal user, set the SUID flag:
sudo chmod +s /usr/local/bin/jltop
