如何标记Prometheus blackbox_exporterendpoint

Question

我有一个带有普罗米修斯的k8s集群和几个带有web应用程序的豆荚。我想从这些网络应用程序中收集度量标准。我使用Prometheus blackbox_exporter来实现这一点。

我配置了服务监视器，部署，工作由普罗米修斯操作员。普罗米修斯收集了度量，但我无法区分它们。例如，
probe_success{endpoint=“http-metrics”,instance=“10.20.0.105:9115”,job=“prometheus-blackbox-exporter”,namespace=“staging”,pod=“prometheus-blackbox-exporter-66fb58ff97-pd6lk”,service=“prometheus-blackbox-exporter”}

我应该做什么来为每个endpoint添加额外的标签？

如何向probe_success度量标准添加诸如target之类的标签？

  blackbox.yaml: |
    modules:
      http_2xx:
        prober: http
        http:
          preferred_ip_protocol: "ipv4"
          tls_config:
            ca_file: "/config/my.pem"
      http_post_4xx:
        prober: http
        http:
          method: POST
          valid_status_codes: [400,404,401,403]
          headers:
            Content-Type: application/json
          body: '{"nonsense"}'
          preferred_ip_protocol: "ipv4"
          tls_config:
            ca_file: "/config/my.pem"

想通了：

port: snmp-exporter
    params:
      module:
      - if_mib # Select which SNMP module to use
      target:
      - 192.168.0.0
    path: "/snmp"
    targetPort: 9116
    honorLabels: true
    relabelings:
            #- action: labelmap
      - sourceLabels: [__param_target]
        #regex: '.*'
        #action: replace
        targetLabel: instance
