CoreDNS

OpsVerse's Kubernetes agent can be used to collect metrics from CoreDNS running in your Kubernetes Cluster.
Prerequisites
OpsVerse Agent should be running in the same cluster where CoreDNS pods are running
Configuration
Add the following YAML snippet to the agent's values.yaml and run the agent based on these instructions.
YAML
observe-agent:
  victoria-metrics-agent:
    extraScrapeConfigs:
      - job_name: 'coredns'
        kubernetes_sd_configs:
          - role: pod
        relabel_configs:
          - source_labels: [__meta_kubernetes_pod_label_k8s_app]
            action: keep
            regex: kube-dns
observe-agent:
  victoria-metrics-agent:
    extraScrapeConfigs:
      - job_name: 'coredns'
        kubernetes_sd_configs:
          - role: pod
        relabel_configs:
          - source_labels: [__meta_kubernetes_pod_label_k8s_app]
            action: keep
            regex: kube-dns

If you already have an extraScrapeConfigs block defined in victoria-metrics-agent in your values.yaml, you can simply append the job to the end of the existing config
Visualization
You can use the community-provided CoreDNS Grafana dashboard to visualise your CoreDNS metrics
