The FZJ-Weather Prometheus Exporter (short: exporter) provides weather data in the format specified for Prometheus Exporters. It consists of two parts:

1. fzj_weather.py: a python script using BeautifulSoup4 and requests to parse and return meteorological data from a weather station inside the Forschungszentrum Jülich (short: FZJ). It does so by parsing the website providing the information.
2. exporter (main.py): uses said script to receive, parse and provide the data to the Prometheus database. Once started, it runs indefinitely until interrupted.

main.py references the weather script and other needed scripts. It therefore marks the entry point of the exporter.

1. Install the package from the corresponding GitHub Repository: pip install git+https://github.com/psyinfra/prometheus_fzj_weather_exporter.git
2. Start the exporter: prometheus_fzj_weather_exporter
3. (from another terminal) curl 127.0.0.1:9184

Or

1. Clone the project: git clone [email protected]:psyinfra/prometheus-fzj-weather-exporter.git
2. Install dependencies from inside the repository: pip install -e .
3. Start the exporter: python prometheus_fzj_weather_exporter/main.py --web.listen-address 127.0.0.1:9184
4. (from another terminal) curl 127.0.0.1:9184

The output of curl 127.0.0.1:9184 has this structure (similar for the other data i.e. air pressure, humidity, wind power, wind direction):

# HELP fzj_weather_air_temperature temperature in celsius
# TYPE fzj_weather_air_temperature gauge
fzj_weather_air_temperature 14.0
