Prometheus Exporter for qBittorrent

Running

Create .env and fill it's contents like shown below:

QBIT_WEBUI_URL=<Your qBittorrent WebUI URL (with schema)>
QBIT_WEBUI_USER=<WebUI username>
QBIT_WEBUI_PASSWORD=<WebUI password>

Example with actual values:

QBIT_WEBUI_URL=http://192.168.67.15:8080
QBIT_WEBUI_USER=admin
QBIT_WEBUI_PASSWORD=qwerty12345

Then run:

pnpm build && pnpm start

Exporter will now listen on port 9167 by default on all interfaces

You can go to your browser and check the metrics at http://127.0.0.1:9167/metrics

After running you can setup your prometheus like with any other exporter:

# assuming you are running both prometheus and this exporter on the same machine
# without containers and etc. otherwise change the target address

       restart: always
       ports:
         - "9167:9167"
       env_file:
         - ./.env
       deploy:
         resources:
           limits:
           memory: 256M
