prometheus-storagebox-exporter

This tool talks to the Hetzner API and gets a list of all Storage Boxes in your account and exports their statistics as Prometheus metrics on <host>:9509/metrics.

Authentication

In the Cloud Console, switch to the project where your storage box is part of and generate a read-only API Token. See the Authentication chapter in the hetzner api docs. This token then needs to be provided as an environment variable.

Usage

You need to provide your api token via environment variables. So after compiling the binary you could run it like

HETZNER_TOKEN='...' ./prometheus-storagebox-exporter

then visit localhost:9505/metrics

To expose the exporter on a different addresse, you can set LISTEN_ADDRESS and set host:port.

Running as Docker container

This exporter can be run as Docker container as well.

First you need to provide your credentials in the .env file.

Then, either build and run the image manually with

docker run -d --name storagebox-exporter --env-file .env fleaz/prometheus-storagebox-exporter

or use compose:

docker compose up -d
