Connectbox Prometheus

A Prometheus exporter for monitoring Compal CH7465LG cable modems. These are sold under the name "Connect Box" by Unitymedia in Germany, Ziggo in the Netherlands and UPC in Switzerland/Austria/Poland. Or as "Virgin Media Super Hub 3" by Virgin Media.

Makes thorough use of compal_CH7465LG_py by @ties (thanks!).

Installation

On your Prometheus server host:

Using pip

1. Create a virtual environment using python3.7 or higher
2. Install the exporter via pip install connectbox-prometheus

Using Docker

Alternatively you could use the provided Dockerfile. We don't provide builds on Docker Hub or similar, so you need to git clone and build it yourself:

git clone https://github.com/mbugert/connectbox-prometheus.git

cd connectbox-prometheus

Choose either docker run or docker-compose.

docker run

To build your own local docker image run docker build -t connectbox-prometheus .

To actually create and run a container named connectbox-prometheus use the following command:

docker run -v connectbox-prometheus-volume:/data -p 9705:9705 --name connectbox-prometheus connectbox-prometheus

The example config.yml found in the root of this repo will be copied to the provided /data volume (e.g. connectbox-prometheus-volume, usually found under /var/lib/docker/volumes/connectbox-prometheus-volume and the container will stop, because you most likely need to modify the given config. See Usage.

After modifying, run docker start connectbox-prometheus to keep the container running.

docker-compose

docker-compose up will automatically build the docker image, start the container the first time to copy the example config.yml and exit again. Now there should be an directory named data where you can find your config.yml. Modify it to your needs. See Usage.

After modifying, run docker-compose up -d to keep the container running.

Usage

This exporter queries exactly one Connect Box as a remote target. To get started, modify config.yml from this repository or start out with the following content:

# Connect Box IP address
ip_address: 192.168.0.1

# Connect Box web interface password
password: WhatEverYourPasswordIs

Then run connectbox_exporter path/to/your/config.yml .

Prometheus Configuration

Add the following to your prometheus.yml:

scrape_configs:
  - job_name: 'connectbox'
    static_configs:
      - targets:
        - localhost:9705

One scrape takes roughly 6 seconds.
