an unofficial prometheus exporter for the Hochwassernachrichtendienst Bayern.
Usage of ./hochwassernachrichtendienst_exporter:
--listenAddress string Address on which to expose metrics (default ":8777")
--metricsPath string Path under which to expose metrics (default "/metrics")
The exporter fetches the station on-demand and therefor needs it the stationId as a HTTP parameter.
Sample curl call: curl http://127.0.0.1:8777/metrics\?station\=10092000 -v
The station parameter can be set by using relabeling. You can find the numeric station id in the respective
URL of the station page at https://www.hnd.bayern.de/pegel/meldestufen
