nws_exporter

Prometheus exporter for the national weather service observation api

Documentation can be found
here.

The endpoints refresh around once every hour or two.
It doesn’t seem like the interval that it gets updated at is too consistent.

All we are doing here is making a GET request to this URL:

https://api.weather.gov/stations//observations/latest

A less than perfect way to find a station near you would be to go to
https://www.weather.gov and click through the map to find where you are,
and that should land you on a page leading with “Current conditions at

(Station Name)”

Once you’ve found the station name, thats all we need to get started. If we
found the station name to be KRKS an example run would look like:

nws_exporter -station KRKS
