nvtop – A great Linux task monitor

nvtop command is a great task monitor for Linux users that monitors NVIDIA, AMD and Intel GPU (graphics processing unit) usage. It is similar to the top command or htop command and can efficiently handle multiple GPUs in your system and display detailed information about them in htop format.

Next let’s take a look at how to install the nvtop command and monitor GPU tasks on your Linux distribution.

nvtop Command – A great Linux task monitor for NVIDIA, AMD and Intel GPUs

The nvtop command is a GPU status viewer based on ncurses (the new curses library that displays information in the terminal) for AMD, Intel and NVIDIA GPUs. In other words, you can use this interactive GPU process viewer on Linux to view the status of the following GPUs:

• AMD GPU using amdgpu driver.
• Intel graphics card using i915 Linux driver.
• Use NVIDIA drivers with NVIDIA GPUs GeForce 600, GeForce 800M, and their successors.

Installing nvtop command on Linux

You can also install the nvtop command on the GPU desktop or server depending on your Linux distribution.

Arch Linux

Run the following pacman command:

$ sudo pacman -Syu nvtop

Gentoo Linux

Use the following emerge command:

linuxmi@linuxmi:~/www.linuxmi.com$ sudo layman -a guru linuxmi@linuxmi:~/www.linuxmi.com$ sudo emerge -av nvtop

Ubuntu Impish (21.10), Debian Buster (stable) and newer versions

Try using apt command or apt-get command:

linuxmi@linuxmi:~/www.linuxmi.com$ sudo apt update linuxmi@linuxmi:~/www.linuxmi.com$ sudo apt install nvtop

Debian Linux 10 users please enable contrib software sources in /etc/apt/sources.list:

deb http://deb.debian.org/debian buster main non-free contrib deb http://deb.debian.org/debian buster-updates main non-free contrib deb http://deb.debian.org/debian-security/ buster/updates main non-free contrib

Then search for it using apt-cache command and install it using sudo apt install nvtop command:

linuxmi@linuxmi:~/www.linuxmi.com$ sudo apt update linuxmi@linuxmi:~/www.linuxmi.com$ sudo apt search nvtop linuxmi@linuxmi:~/www.linuxmi.com$ sudo apt-cache policy nvtop

All other Linux distributions

Try using the snap command. For example:

linuxmi@linuxmi:~/www.linuxmi.com$ snap search nvtop linuxmi@linuxmi:~/www.linuxmi.com$ sudo snap install nvtop

Next, add the function to kill GPU processes in nvtop:

linuxmi@linuxmi:~/www.linuxmi.com$ sudo snap connect nvtop:process-control

You can also easily add the ability to view GPU information (fans, PCIe, power supplies, etc.) as follows:

linuxmi@linuxmi:~/www.linuxmi.com$ sudo snap connect nvtop:hardware-observe

Here's how to add AMD GPU process list support:

linuxmi@linuxmi:~/www.linuxmi.com$sudo snap connect nvtop:system-observe

You may need a workaround to get per-process GPU usage. For example:

linuxmi@linuxmi:~/www.linuxmi.com$ sudo snap connect nvtop:kubernetes-support

How to use Docker nvtop image

Please try the following commands in a Linux terminal. You must have a working Docker installation. For example:

linuxmi@linuxmi:~/www.linuxmi.com$git clone https://github.com/Syllo/nvtop.git linuxmi@linuxmi:~/www.linuxmi.com$cd nvtop linuxmi@linuxmi:~/www.linuxmi.com/nvtop$ sudo docker build --tag nvtop . linuxmi@linuxmi:~/www.linuxmi.com/nvtop$ sudo docker run -it --rm --runtime=nvidia --gpus=all --pid=host nvtop

Getting started with nvtop

Now that the tool is installed, it’s time to try it out. You just need to enter the following command:

linuxmi@linuxmi:~/www.linuxmi.com$ nvtop

You can also specify the delay between updates in tenths of a second. For example:

linuxmi@linuxmi:~/www.linuxmi.com$nvtop -d 0.25

Do you want monochrome mode? Here's how to disable colored output:

linuxmi@linuxmi:~/www.linuxmi.com$ nvtop -C

Here's how to display only one bar, corresponding to the maximum value across all GPUs:

linuxmi@linuxmi:~/www.linuxmi.com$ nvtop -p

in conclusion:

I find nvtop very useful when I need to see what is stress testing my GPU and key information like GPU temperature or fan speed. You can use this tool to quickly kill a process that is using up all GPU resources without having to use the ps command/grep command and then kill the PID. Most modern applications such as Firefox, Chrome, and code written in Python can use dedicated NVIDIA or AMD GPUs. Therefore, it is very useful to have this gadget. Might as well give it a try.

Get help with nvtop

You can read the nvtop manual page in the project repository offline or online. For example, try using the man command or passing the -h option like this:

nvtop -h
