​​Key metrics for CoreDNS monitoring

CoreDNS is an open source DNS server that provides service discovery within a Kubernetes cluster and can resolve requests for internet domain names. Monitoring CoreDNS performance metrics, such as request processing latency and update latency, can help detect potential issues affecting the overall performance of your applications running on Kubernetes. Additionally, monitoring resource usage metrics like memory utilization and CPU utilization can ensure that your autoscaling parameters and container resource requests and limits are appropriate for managing CoreDNS workloads effectively.
