【问题描述】：

我在 kubernetes 集群上运行 kube-prometheus-stack 以及 prometheus-blackbox-exporter。我想监控多个 http 目标。我尝试使用 servicemonitor 进行设置，但是当我添加目标时，目标没有得到正确的标签

servicemonitor yaml：

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  annotations:
    meta.helm.sh/release-name: blackbox
    meta.helm.sh/release-namespace: default
  generation: 1
  labels:
    app.kubernetes.io/instance: blackbox
    app.kubernetes.io/managed-by: Helm
    app.kubernetes.io/name: prometheus-blackbox-exporter
    app.kubernetes.io/version: 0.20.0
    helm.sh/chart: prometheus-blackbox-exporter-5.7.0
    release: kube-prometheus
  name: blackbox-prometheus-blackbox-exporter
  namespace: default
spec:
  endpoints:
    - interval: 10s
      path: /probe
      port: http
      scheme: http
      params:
        module: 
        - http_2xx
        target:
          - https://google.com
          - https://example.com
      metricRelabelings:
      - sourceLabels: [__address__]
        targetLabel: __param_target
  jobLabel: kube-prometheus
  selector:
    matchLabels:
      app.kubernetes.io/instance: blackbox
      app.kubernetes.io/name: prometheus-blackbox-exporter

但在 grafana 中，我只能得到一个正确的实例标签： grafana instances

【解决方案1】：

spec.endpoints 是一个list。在 yaml 中，每个列表元素都使用 dash 定义。所以你必须将你的服务监视器yaml修改为：

spec:
  endpoints:
  - interval: 10s
    path: /probe
    port: metrics
    params:
      module:
      - http_2xx
      target:
      - https://www.google.com
    relabelings:
      - sourceLabels: [__param_target]
        targetLabel: target

  - interval: 10s
    path: /probe
    port: metrics
    params:
      module:
      - http_2xx
      target:
      - https://www.example.com
    relabelings:
      - sourceLabels: [__param_target]
        targetLabel: target

有效 like it is shown here
