Integrate wmbusmeters with Prometheus

https://prometheus.io/

1. Add a shell configuration key to /etc/wmbusmeters.conf:

   shell=/usr/bin/curl localhost:9144/webhook --data "$METER_JSON"
   

2. Create a grok_exporter configuration:

   global:
     config_version: 3
   input:
     type: webhook
     webhook_path: /webhook
     webhook_format: json_single
     webhook_json_selector: .meter
   metrics:
   - type: gauge
     name: water_consumption
     help: Cubic meters of water used
     match: 'multical21'
     value: ''
     cumulative: false
     labels:
    media: ''
    id: ''
    name: ''
   server:
     host: "[::]"
     port: 9144
   

3. Start grok_exporter

   docker-compose up -d
   

   With: ``` version: ‘3’ services: grok_exporter: image: magentaaps/grok_exporter:latest-rc command: -config /srv/grok_exporter_config.yml ports:

   • 9144:9144 volumes:
   • ./grok_exporter_config.yml:/srv/grok_exporter_config.yml ```

4. Start wmbusmetersd

5. Verify that metrics are flowing:

   curl localhost:9144/metrics
   

   Yields:

   ...
   # HELP water_consumption Cubic meters of water used
   # TYPE water_consumption gauge
   water_consumption{id="11111111",media="cold water",name="MyColdTapWater"} 1.326
   

6. Add grok_exporter as a scrape_target to Prometheus.
