Question

我想收集PersistentVolumeClaim的指标以了解剩余的存储空间。但是按照下面的配置，我无法获得有关PVC的指标，例如

kubelet_volume_stats_available_bytes{persistentvolumeclaim="your-pvc"}
kubelet_volume_stats_capacity_bytes{persistentvolumeclaim="your-pvc"}

我正在使用Prometheus版本v2.12.0和EKS（K8S版本1.12）

这是我的普罗米修斯配置。

- job_name: 'kubernetes-nodes'
      scheme: https
      tls_config:
        ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
      bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token

      kubernetes_sd_configs:
      - role: node

      relabel_configs:
      - action: labelmap
        regex: __meta_kubernetes_node_label_(.+)
      - target_label: __address__
        replacement: kubernetes.default.svc:443
      - source_labels: [__meta_kubernetes_node_name]
        regex: (.+)
        target_label: __metrics_path__
        replacement: /api/v1/nodes/${1}/proxy/metrics

这里是部署：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: prometheus-server
  namespace: monitoring
  labels:
    app: prometheus-server
spec:
  replicas: 1
  selector:
    matchLabels:
      app: prometheus-server
  template:
    metadata:
      labels:
        app: prometheus-server
    spec:
      serviceAccountName: monitoring
      securityContext:
        fsGroup: 2000
        runAsNonRoot: true
        runAsUser: 1000
      containers:
        - name: prometheus
          image: prom/prometheus:v2.12.0
          args:
            - "--config.file=/etc/prometheus/prometheus.yml"
            - "--storage.tsdb.path=/prometheus/"
          ports:
            - containerPort: 9090
          volumeMounts:
            - name: prometheus-config-volume
              mountPath: /etc/prometheus/
            - name: prometheus-data
              mountPath: /prometheus/
      volumes:
        - name: prometheus-config-volume
          configMap:
            defaultMode: 420
            name: prometheus-server-conf

        - name: prometheus-data
          persistentVolumeClaim:
            claimName: prometheus-data
