prometheus监控容器

一、基于kubernetes的cAdvisor监控容器

1、修改prometheus数据抓取配置文件
  - job_name: 'kubernetes-cadvisor'
    kubernetes_sd_configs:
    - role: node
    scheme: https
    tls_config:
      ca_file: /var/run/secrets/kubernetes.io/serviceaccount/ca.crt
    bearer_token_file: /var/run/secrets/kubernetes.io/serviceaccount/token
    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/cadvisor
