The record

Purpose: dnshealth_exporter monitors DNS zone health and exposes Prometheus metrics for dashboards and alerting.
Checks: The README says SOA, recursion-available, and glue consistency checks are implemented; the project is marked early development.
Intended use: It is designed to surface DNS health signals such as parent delegation, nameserver consistency, SOA correctness, and MX validity.
Integrations: The project describes using Prometheus metrics with Grafana dashboards and alerting, with thresholds and alert rules handled in Grafana or Alertmanager.
Demo: A bundled Docker Compose demo runs the exporter, Prometheus, Grafana with a pre-imported dashboard, and a CoreDNS hierarchy.
Installation: The README documents building from source with Go 1.26 or later and running the exporter with a YAML configuration file.
Metrics: The exporter serves metrics at the local endpoint http://localhost:9199/metrics, refreshing on a configurable probe interval that defaults to 60 seconds.
Configuration: Configuration can be reloaded without restarting, either by sending SIGHUP or by posting to /-/reload.
Limits: The README says the metrics endpoint returns HTTP 503 until the first probe cycle completes.
Security: The repository lists an Apache License 2.0 and does not state security certifications or compliance claims in the README.
Operations: The README provides an example systemd service configuration with restart-on-failure and reload support.
Support: The README provides a demo walkthrough and troubleshooting instructions but does not specify a support service or response commitment.
