Exports the expiration time of your domains as prometheus metrics.
./domain_exporter -b ":9222"
Or with docker:
docker run -p 9222:9222 caarlos0/domain_exporter
On the prometheus settings, add the domain_exporter prober:
- job_name: domain
metrics_path: /probe
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: domain
- 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.
