配置http的监控，prometheus.yml

  - job_name: "http_status"
    metrics_path: /probe
    params:
      module: [http_2xx]
    static_configs:
      - targets: ["http://www.xiaomi.com","http://www.baidu.com"]
        labels:
          instance: http_status
          group: web
    relabel_configs:
      - source_labels: [__address__] #relabel通过将__address__(当前目标地址)写入__param_target标签来创建一个label.
        target_label: __param_target #监控目标www.xiaomi.com,作为__address__的value
      - source_labels: [__param_target] #监控目标
        target_label: url #将监控目标与url创建一个label
      - target_label: __address__
        replacement: 10.211.55.20:9115

重启prometheus，查看blackbox

配置ICMP的监控,prometheus.yml

  - job_name: "ping_status"
    metrics_path: /probe
    params:
      module: [icmp]
    static_configs:
      - targets: ["10.211.55.21","10.211.55.22"]
        labels:
          instance: 'ping_status'
          group: 'icmp'
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: ip #将ip与__param_target创建一个label
      - target_label: __address__
        replacement: 10.211.55.20:9115

重启prometheus

端口监控，prometheus.yml

  - job_name: "port_status"
    metrics_path: /probe
    params:
      module: [tcp_connect]
    static_configs:
      - targets: ["10.211.55.20:6443","10.211.55.26:9100"]
        labels:
          instance: 'port_status'
          group: 'port'
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: ip #将ip与__param_target创建一个label
      - target_label: __address__
        replacement: 10.211.55.20:9115
