Port for obtaining coredns metrics. The default zone listening IP address is {$POD_IP}:9153. Retain the default value. Otherwise, Prometheus cannot collect the metrics.
If you use on-premises Prometheus to monitor Kubernetes clusters, you can observe related metrics on Prometheus and configure alarms for the key metrics. For details, see prometheus.
