CoreDNS

StackGen's Kubernetes agent can be used to collect metrics from CoreDNS running in your Kubernetes Cluster.

Prerequisites

• StackGen 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.

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

warning

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
