Our verdict on dnshealth_exporter

dnshealth_exporter is an open-source Prometheus exporter for monitoring DNS zone health. It is aimed at operators already running Prometheus and Grafana who need checks for delegation, parent and child nameserver consistency, SOA correctness, MX validity, glue consistency, and recursion availability. The project runs on Linux in a self-hosted environment and exposes DNS health metrics for analysis and alerting.

Its ecosystem fit is a clear strength. The exporter integrates with Prometheus and supports Grafana dashboards and Alertmanager workflows, while Docker Compose and CoreDNS are included in its integration scope. A bundled Docker Compose demo brings together Prometheus, Grafana, and CoreDNS, giving infrastructure teams a defined path for evaluating the monitoring workflow. Configuration uses YAML, and configuration reloads can occur without restarting the exporter, which helps when DNS monitoring rules change.

The product has a deliberately narrow focus on DNS zone health rather than broad DNS change management. Its implemented checks cover several operational failure points, including delegation, SOA, MX, glue, nameserver consistency, and recursion availability. That makes it a practical fit for teams that already maintain their own observability stack and want DNS-specific metrics within it. Teams needing record-change monitoring, a vendor-hosted service, or a more mature commercial support model should choose an alternative. dnshealth_exporter is best suited to technically capable Prometheus users who accept responsibility for deployment and maintenance.
