python_systemstats

Reads Linux System statistics, like System Load, CPU/Ram Usage and Disk utilization with a python script. Also you can publish the data to a MQTT Broker. So it is possible to use the data somewhere else, for example in your smarthome enviroment. For that usage, there is a homie convention based script, which you can run as systemd service.

Requirements

you need to install the following requirements for python3

apt update && apt install python3 python3-pip python3-paho-mqtt python3-gpiozero python3-psutil python3-systemd

# or via pip3
pip3 install paho-mqtt
pip3 install psutil
pip3 install gpiozero
pip3 install systemd

Also you should have a MQTT Broker

Thats enough for a short test:

cd /usr/local/sbin
wget https://github.com/alaub81/python_systemstats/raw/main/systemstats.py
chmod +x systemstats.py 
systemstats.py

Now you should see the following output:

---System Informations---
System Uptime: 19:40:41.538989 - 1181 min
CPU Temperatur: 37.4 °C
CPU Usage: 1 %
Load average: 0.23 0.25 0.16
Ram Total: 368.4 MiB
Ram Used: 35.7 MiB
Ram Free: 137.0 MiB
Ram Usage: 28.3 %
Disk Total: 29.0 GiB
Disk Used: 2.1 GiB
Disk Free: 25.7 GiB
Disk Usage: 7.4 %

Installing the systemstats-homie.py Script as systemd service

Installation is easy, just download the systemstats-homie.py and systemstats-homie.service, configure them und ready it is.

cd /usr/local/sbin
wget https://github.com/alaub81/python_systemstats/raw/main/systemstats-homie.py
chmod +x systemstats-homie.py 
nano systemstats-homie.py

Now configure the part on top of the script with your data. After that, just install the systemd service and start it:

cd /etc/systemd/system
wget https://github.com/alaub81/python_systemstats/raw/main/systemstats-homie.service
systemctl daemon-reload
systemctl enable systemstats-homie.service
systemctl start systemstats-homie.service

Now check if everything is running

systemctl status systemstats-homie.service

and also check the data is published to the mqtt broker.
