pi-status

pi-status is a resource monitoring web application. It provides real-time information about the device's RAM, storage, CPU temperature and usage, processes' data, and network usage. It comes with a user friendly, mobile first front-end

It can be compiled for other architectures and will run on any Linux device with a modern kernel, but the temperature readings for the CPU are going to be wrong if they're not found in /sys/class/thermal/thermal_zone0/temp, independently of CPU architecture

Usage

By default, pi-status will only be available to connections coming from private networks, hiding it from public ones

Use -f to make the monitored data available to anyone on the internet (this option is necessary when running pi-status in a Docker container)

Installation and running

You can choose to compile and run pi-status natively or build a Docker image and run it in a container, though the latter option requires making the monitored resources necessarily publicly exposed, and only filterable through a firewall

Requirements

• Rust toolchain
• NodeJS

Compilation

To compile, simply run make. You can then run pi-status with the command ./back/target/release/pi-status from the project's root folder

You probably don't want to leave a shell with pi-status constantly running, an alternative is running it as a systemd service, an example configuration file for that is shown below

[Unit]
Description=pi-status resource monitor
After=network.target

[Service]
Type=simple
User=<user>
WorkingDirectory=<your-pi-status-directory>
ExecStart=<your-pi-status-directory>/back/target/release/pi-status
Restart=on-failure

[Install]
WantedBy=multi-user.target

Cross compilation

If you want to cross compile for your RPi 3/4 that is also possible with make arm64. This requires to have the aarch64 Rust and GNU toolchains installed

Building the Docker image

Requirements

• Docker, including compose and buildx plugins
• If cross compiling: qemu-user-static and qemu-user-static-binfmt

The quoted packages are found in Arch Linux repositories, you should find the corresponding ones for your distribution of choice

Building

1. Clone the repository

The second step depends on your Raspberry Pi target

2. RPi 3/4: make docker-arm64

   RPi 2: make docker-armv7

If for some reason you want to try containerized pi-status on a amd64 machine, make docker-amd64 is also available

After building the image and having it transferred to the target machine

3. Remove intermediate images on your build machine with docker image prune -f and, if desired, remove build images manually (rust, node, alpine)
4. Edit the docker-compose.yaml for arguments and additional volumes mounting (this is necessary for the containerized pi-status instance to be able to gather storage information about them)
5. Run on target with docker compose up

Endpoints

• / -> the web page to view the monitored resources data
• /ws_data -> WebSocket endpoint for monitored resources data in JSON format messages
