I am new to kubernetes. I want to get container metrics from all the cAdvisor pods present in kubernetes cluster. I have deployed cAdvisor as daemonset on the cluster. Below is the yaml file.
cAdvisor daemonset yaml file for kubernetes:
apiVersion: apps/v1 # for versions before 1.8.0 use extensions/v1beta1 [apps/v1beta2] kind: DaemonSet metadata: name: cadvisor namespace: kube-system labels: app: cadvisor spec: selector: matchLabels: name: cadvisor template: metadata: labels: name: cadvisor spec: tolerations: - key: node-role.kubernetes.io/master effect: NoSchedule containers: - name: cadvisor image: google/cadvisor:latest volumeMounts: - name: rootfs mountPath: /rootfs readOnly: true - name: var-run mountPath: /var/run readOnly: false - name: sys mountPath: /sys readOnly: true - name: docker mountPath: /var/lib/docker readOnly: true ports: - name: http containerPort: 8080 protocol: TCP args: - --housekeeping_interval=10s terminationGracePeriodSeconds: 30 volumes: - name: rootfs hostPath: path: / - name: var-run hostPath: path: /var/run - name: sys hostPath: path: /sys - name: docker hostPath: path: /var/lib/docker
I can only see the container metrics being scraped from only one of the cAdvisor pod on grafana. How to get container metrics from other pods too?
Note: I can see cAdvisor deployed on each agentpools. But prometheus identifies only one.
