domain_exporter

Exports the expiration time of your domains as prometheus metrics.

Environment variables

• DOMAIN_EXPORTER_URL_PREFIX — use when HTTP endpoint served with a prefix, e.g.: For this endpoint http://example.org/exporters/domains set to /exporters/domains. Not really required since useful only to prevent breaking human-oriented links. Defaults to empty string.

Configuration

On the Prometheus settings, add the domain_exporter probe:

- job_name: domain
  metrics_path: /probe
  relabel_configs:
    - source_labels: [__address__]
      target_label: __param_target
    - target_label: __address__
      replacement: localhost:9222 # domain_exporter address
  static_configs:
    - targets:
      - carlosbecker.com
      - carinebecker.com
      - watchub.pw

It works more or less like Prometheus's blackbox_exporter.

Alerting rules examples can be found on the _examples folder.

You can configure domain_exporter to always export metrics for specific domains. Create configuration file (host field is optional):

domains:
- google.com
- name: reddit.com        
  host: whois.godaddy.com # <-- custom whois server for reddit.com

And pass file path as argument to domain_exporter:

domain_exporter --config=domains.yaml

Notice that if you do that, results are cached, and you should change your job metrics_path to /metrics instead.
