Pi Monitor

Python utility to get Raspberry Pi metrics. This is an experimental utility, use at your own risk :)

This is just a very simple Python script using a http server to provide some Raspberry Pi metrics via REST calls, like temperature, load average and more.

Usage

The server will make a single endpoint available on the default port 8088: http://YOUR_IP:8088/monitor.json that will return a JSON like this:

{
  "soc_temperature": 50.5,
  "uptime": 18551.34,
  "load_average": [0.0, 0.2, 0.1],
  "kernel_release": "5.4.51-v7+",
  "memory": {
    "total_memory": 441416,
    "free_memory": 90536,
    "available_memory": 279512
  }
}

Installation

Automatic

wget -O - https://raw.githubusercontent.com/draiko913/pi_monitor/master/install.sh | sudo bash

Manual

You can download the files manually and run it the way you like. If you don't want Pi Monitor to run as a service you can just run as python3 pi_monitor.py

Configuration

If you're running it using the automatic installation you can change the username and default port in which Pi Monitor is running by changing the following settings on your pi-monitor.service

[Service]
ExecStart=/usr/bin/python3 -u /usr/local/bin/pi-monitor.py 8088
User=pi

Before doing so, make sure to stop the service with sudo systemctl stop pi-monitor.service and then start it again after your changes with sudo systemctl start pi-monitor.service

If you're running it manually you can just change the default port by sending it as a parameter like: python3 pi_monitor.py 8181

Compatibility

This was tested on Raspberry Pi OS (32 bit), kernel 5.4.51-v7+
