Install Hwmon

Check the python version in Linux

Before installing or running Hwmon it is essential to have a system with GNU/Linux along with python 3. To see the version of Python you have installed on your system you have to execute these sentences in the terminal:

python --version

python3 --version

And you will keep the name (without -version) that returns python 3.xx. Where de xx can be any number (ex: 3.5, 3.8, etc...).

In this case, we will keep the name "python3", since it is the "executable" of version 3 for python.

Install python-pip

To install Hwmon you can choose to do it in an automatic or manual way, but it is recommended to do the manual installation since it is the most updated version compared to the automatic version.

Regardless of whether it is manual or not, you must have pip or pip3 installed. Depending on the name where the python3 version is hosted, it will have to be installed in one way or another.

python3 -> sudo apt install python3-pip
python -> sudo apt install python-pip

Install Hwmon

If you want to install the automatic version, you will only have to execute this sentence:

python3 -> pip3 install hwmon
python -> pip install hwmon

In case it is manual, you will have to follow these steps:

Installing git if you don't have it installed
```
sudo apt install git-all
```

Execute these sentences at the terminal

git clone https://github.com/Guillermo-C-A/Hwmon-python.git
cd Hwmon-python
python3 -> pip3 install .
python -> pip install .

Ex:

Use our terminal interface to see everything our library has to offer :)

cd bin
python3 -> python3 hwmon-cli --help
python -> python hwmon-cli --help

Ex:

python3 -> python3 hwmon-cli --sensors
python -> python hwmon-cli --sensors

More examples:

python3 -> python3 hwmon-cli --cpu --gpu --sensors
python -> python hwmon-cli --cpu --gpu --sensors

We are open to new ideas and people who want to improve this project, so feel free to open pull requests or leave us your opinions/problems with the application in this section.

Don't forget to give a star to this repository :D

Disclaimer

The information presented in this library may vary depending on the distribution or kernel being executed, to the point of giving error in certain functions such as GPU.

In case this happens, inform us of the error so that we can fix the fault :)

Tested and stable kernels:

5.8 (Ubuntu 20)
5.4.0.42.46 (Ubuntu 20)

It has also been tested on three different computers with AMD CPU and GPU configurations successfully and stably

New features

We are currently working in parallel to develop the interfaces for this library. You can download the terminal interface this link

In addition, the desktop GUI is in the process of being created.

Motivations to create Hwmon

Hwmon has been created with the intention of replacing Linux libraries and APIs which obtain system information without the need to depend on dependencies outside a standard Linux system.

The only requirements for running Hwmon on a system are:

The OS is Linux
Have python 3
Install hwmon library

Hwmon is also a library developed expressly by and for Python 3 with functions that are easy to understand and operate, which read and synthesize in the same library all the useful information for monitoring a Linux system that can be found in the /sys, /proc and /dev folders. So only the information that the system itself has recorded will be obtained.

Why use Hwmon instead of other library?

As already mentioned, Hwmon does not require any dependencies or programs and is a library created with the standard Python 3 libraries. Which is not the case like other library/software such as:

Pysensors
lm-sensors
psutil

Where you need files and other softwares to be able to work, so if you're missing some of that, it just doesn't work. They are also heavier solutions in terms of file sizes than Hwmon.

Is it really a viable alternative to lm-sensors?

Yes. Hwmon is able to return and print the same information that is obtained when installing and running sensors.

And it even prints the information on the screen in a nice and friendly way so that it is more useful and easy to understand.

What information can I get from Hwmon and where does he get it from?

Hwmon is able to extract:

Information from the sensors available on the computer
Processor information
System memory information
Sent and received packet information
USB devices connected to the computer
Disks connected to the computer
BIOS information
GPU information

All this information is extracted respectively from the following sites:

Sensors: /sys/class/hwmon
CPU: /proc/cpuinfo and /proc/stat
RAM: /proc/meminfo
Network: /proc/net/dev
USB: /dev/input/by-id
Disks: /dev/disk/by-id
GPU: /sys/class/graphics or /sys/class/drm/card0/device/
BIOS: /sys/class/dmi/id/

How to use and call the library?

from hwmon import Hwmon
