The FZJ-Weather Prometheus Exporter (short: exporter) is an exporter compatible with the Prometheus database. It consists of two parts:
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.- exporter (
main.py
): uses said script to receive, parse and provide the data to the Prometheus database. Once started, it runs indefinitely until interrupt.
main.py
references the weather script and other needed scripts. It
therefore marks the entry point of the exporter.
The exporter is not finished yet and full functionality is not guaranteed yet. Installing and starting can be tested already.
- Install the package from the corresponding Github Repository:
pip install git+https://github.com/o-druska/fzj-weather-prometheus-exporter
- Start the exporter:
prometheus_fzj_weather_exporter
To test the exporter, you can host the script on your own machine:
prometheus_fzj_weather_exporter
- (from another terminal)
curl 127.0.0.1:9840
Running curl 127.0.0.1:9840
should give you an output of similar
structure like this:
# HELP fzj_weather_air_temperature temperature in celsius
# TYPE fzj_weather_air_temperature gauge
fzj_weather_air_temperature 14.0
The default port in the script is 9840.
Change the port with prometheus_fzj_weather_exporter --port <port>
(The output should be similar for other data points, i.e. humidity)
