Prometheus metrics exporter for api.weather.gov
nws_exporter fetches weather information for a particular [NWS station] using the [api.weather.gov] API and emits
it as Prometheus metrics. Users must pick a particular station to fetch weather information from. The following
metrics are emitted when available (not all fields are available for all stations).
nws_elevation_meters{station=$STATION_ID} - Elevation of the station, in meters.nws_temperature_degrees{station=$STATION_ID} - Temperature, in degrees celsius.nws_dewpoint_degrees{station=$STATION_ID} - Dewpoint, in degrees celsius.nws_barometric_pressure_pascals{station=$STATION_ID} - Barometric pressure, in pascals.nws_visibility_meters{station=$STATION_ID} - Visibility, in meters.nws_relative_humidity{station=$STATION_ID} - Relative humidity (0-100).nws_wind_chill_degrees{station=$STATION_ID} - Temperature with wind chill, in degrees celsius.nws_exporter is a Rust program and must be built from source using a Rust toolchain.

You can run nws_exporter as a Systemd service using the provided unit file. This
unit file assumes that you have copied the resulting nws_exporter binary to /usr/local/bin/nws_exporter.
text
sudo cp target/release/nws_exporter /usr/local/bin/nws_exporter
sudo cp ext/nws_exporter.service /etc/systemd/system/nws_exporter.service
sudo systemctl daemon-reload
sudo systemctl enable nws_exporter.service
sudo systemctl start nws_exporter.serivce
Prometheus metrics are exposed on port 9782 at /metrics. Once nws_exporter
is running, configure scrapes of it by your Prometheus server. Add the host running
nws_exporter as a target under the Prometheus scrape_configs section as described by
the example below.
```yaml
global: scrapeinterval: 15s evaluationinterval: 15s externallabels: monitor: 'myprom'
scrapeconfigs: - jobname: nwsexporter staticconfigs: - targets: ['example:9782'] ```
