CoreDNS Integration

CoreDNS Integration

Xitoring's CoreDNS integration simplifies monitoring by automatically collecting key DNS metrics, providing real-time insights into DNS request handling, cache performance, and overall server health. This integration enables rapid identification and resolution of DNS-related issues, ensuring reliable and efficient DNS services.

Enable CoreDNS integration

To enable CoreDNS integration, execute the following command on the server where CoreDNS is installed:

xitogent integrate

Select CoreDNS from the list of available integrations. Xitogent will automatically generate the configuration file at /etc/xitogent/integrations/coredns_integration.conf and immediately begin collecting metrics.

Note Xitogent expects CoreDNS metrics to be exposed via the standard Prometheus metrics endpoint (usually at http://localhost:9153/metrics). Ensure CoreDNS is configured to expose metrics at this endpoint.

Setup Triggers for CoreDNS integration

Use Triggers to transform raw CoreDNS metrics into actionable alerts. Recommended trigger patterns include:

  • High DNS Panic Rate

    • Condition: coredns_panics_total > 0 within 5 min

  • Cache Performance Alert

    • Condition: coredns_cache_hit_percentage < 80 within 10 min

Next steps

  • Create dashboards to visualize DNS request trends, response rates, and cache efficiency.
  • Correlate CoreDNS metrics with server resource usage metrics to quickly diagnose performance bottlenecks.
