普罗米修斯在GKE中没有收到来自cadvisor的度量

Question

嘿，

null

    - job_name: kubernetes-cadvisor
      honor_timestamps: true
      scrape_interval: 15s
      scrape_timeout: 10s
      metrics_path: /metrics/cadvisor
      scheme: https
      bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
      tls_config:
        ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
        insecure_skip_verify: true
      kubernetes_sd_configs:
      - role: node
      relabel_configs:
        - action: labelmap
          regex: __meta_kubernetes_node_label_(.+)

如果有人有经验得到这个配置，我肯定会感谢一些帮助调试。

干杯

我能够挖掘一个博客，其中有一个对我有效的示例配置。cadvisor（和kubelet）度量标准的GKEendpoint不同于文档示例中的标准endpoint。以下是我在普罗米修斯工作中的一段摘录：

    - job_name: kubernetes-cadvisor
      honor_timestamps: true
      scrape_interval: 15s
      scrape_timeout: 10s
      metrics_path: /metrics/cadvisor
      scheme: https
      bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
      tls_config:
        ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
        insecure_skip_verify: true
      kubernetes_sd_configs:
      - role: node
      relabel_configs:
        - action: labelmap
          regex: __meta_kubernetes_node_label_(.+)
        - target_label: __address__
          replacement: kubernetes.default.svc.cluster.local:443
        - source_labels: [__meta_kubernetes_node_name]
          regex: (.+)
          target_label: __metrics_path__
          replacement: /api/v1/nodes/${1}/proxy/metrics/cadvisor
    - job_name: kubernetes-kubelet
      honor_timestamps: true
      scrape_interval: 15s
      scrape_timeout: 10s
      metrics_path: /metrics
      scheme: https
      bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
      tls_config:
        ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
        insecure_skip_verify: true
      kubernetes_sd_configs:
      - role: node
      relabel_configs:
      - action: labelmap
        regex: __meta_kubernetes_node_label_(.+)
      - target_label: __address__
        replacement: kubernetes.default.svc.cluster.local:443
      - target_label: __metrics_path__
        source_labels: [__meta_kubernetes_node_name]
        regex: (.+)
        replacement: /api/v1/nodes/${1}/proxy/metrics
