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 > 0within 5 min
- Condition:
Cache Performance Alert
- Condition:
coredns_cache_hit_percentage < 80within 10 min
- Condition:
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.
