Elastic Stack Elasticsearch
, , ,

I have installed the Elasticsearch(8.16) and kibana(8.16) using RPMs in Centos vm.Also installed Metricbeats (8.16) in the centos vm using RPMS.

In the same vm i have kubernetes cluster and our application is running in the k3s cluster.I am trying to capture the kubernetes metrics and see that in Kibana dashboard.

Issue :
I am able to see the namesapce details in the dashboard but the pod, deployment fields i am getting as no data found. like this attached screenshot.

/etc/metricbeat/modules.d/kubernetes.yml

Node metrics, from kubelet:

  • module: kubernetes
    metricsets:
    • node
    • pod
    • system
    • volume
      period: 10s
      enabled: true
      hosts: ["https://<127.0.0.1>:<6443>"]
      bearer_token_file: /var/lib/metricbeat/kubernetes-app-token (This is the self signed token )
      ssl.verification_mode: "none"
      ssl.certificate_authorities: ["/var/lib/rancher/k3s/server/tls/client-ca.crt"]
      ssl.certificate: "/var/lib/rancher/k3s/server/tls/client-kube-apiserver.crt"
      ssl.key: "/var/lib/rancher/k3s/server/tls/client-kube-apiserver.key"
      add_metadata: true
      kubeconfig: "/etc/rancher/k3s/k3s.yaml"
      node: node2
      namespace: default

Below is the error message i am getting in the logs of Metricbeat :
