Prometheus配置用于刮取kube荚度量

Question

我有下面的prometheus配置来获取kubernetes豆荚的度量，但是在prometheus中，我只能看到两个与Kube_pod_CPU、Kube_pod_memory相关的度量，而没有任何其他与荚相关的度量。如果有任何配置问题，请提供任何帮助。

- job_name: 'kubernetes-pods'
  scrape_interval: 15s
  scrape_timeout: 10s
  metrics_path: /metrics
  scheme: http
  kubernetes_sd_configs:
   - role: pod
     namespaces:
       names: ["namespace-name"]
  relabel_configs:
  - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_scrape]
    action: keep
    separator: ":"
    replacement: $1
    regex: true
  - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_path]
    action: replace
    separator: ":"
    replacement: $1
    target_label: __metrics_path__
    regex: (.+)
  - source_labels: [__address__, __meta_kubernetes_pod_annotation_prometheus_io_port]
    action: replace
    separator: ":"
/prometheus-kubernetes.yml
    regex: (.+):(?:\d+);(\d+)
    #regex: ([^:]+)(?::\d+)?;(\d+)
    replacement: ${1}:${2}
    target_label: __address__
  - source_labels: [__meta_kubernetes_pod_container_name]
    action: keep
    regex: prometheus.*
  - action: labelmap
    separator: ":"
    replacement: $1
    regex: __meta_kubernetes_pod_label_(.+)
  - source_labels: [__meta_kubernetes_namespace]
    separator: ":"
    replacement: $1
    action: replace
    target_label: kubernetes_namespace
  - source_labels: [__meta_kubernetes_pod_name]
    separator: ":"
    replacement: $1
    action: replace
    target_label: kubernetes_pod_name

谢谢

> You have to add this three annotation to your deployment:

prometheus.io/scrape: 'true'
prometheus.io/path: 'metrics'
prometheus.io/port: '80'
How it will work?

Look at the kubernetes-pods job of config-map.yaml you are using to configure prometheus,



- job_name: 'kubernetes-pods'

        kubernetes_sd_configs:
        - role: pod

        relabel_configs:
        - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_scrape]
          action: keep
          regex: true
        - source_labels: [__meta_kubernetes_pod_annotation_prometheus_io_path]
          action: replace
          target_label: __metrics_path__
          regex: (.+)
        - source_labels: [__address__, __meta_kubernetes_pod_annotation_prometheus_io_port]
          action: replace
          regex: ([^:]+)(?::\d+)?;(\d+)
          replacement: $1:$2
          target_label: __address__
        - action: labelmap
          regex: __meta_kubernetes_pod_label_(.+)
        - source_labels: [__meta_kubernetes_namespace]
          action: replace
          target_label: kubernetes_namespace
        - source_labels: [__meta_kubernetes_pod_name]
          action: replace
          target_label: kubernetes_pod_name
