这个可以参考 laradock 用变量哦
#填写你的 blackboxip
 vim  prometheus/prometheus.yml

        replacement: "10.3.10.124:9115"  # Blackbox exporter.
        #replacement: "blackbox_exporter:9115"  # Blackbox exporter.

重载
curl -X POST http://127.0.0.1:9090/-/reload

<http_probe>可配置参数 有空要看一下加强一下

9965号模板，数据源选择Prometheus 模板下载地址 https://grafana.com/grafana/dashboards/9965

可以直接进去容器里面安装
此模板需要安装饼状图插件 下载地址 https://grafana.com/grafana/plugins/grafana-piechart-panel
安装插件，重启grafana生效。

 grafana-cli plugins install grafana-piechart-panel
 service grafana-server restart

网络探测监控的操作还有HTTPS DNS TCP ICMP  SSH etc 
<pre>
监控主机存活状态

编辑prometheus配置文件


最后一行添加

最后一行添加

  - job_name: node_status
    metrics_path: /probe
    params:
      module: [icmp]
    static_configs:
      - targets: ['10.165.94.31']
        labels:
          instance: node_status
          group: 'node'

      - source_labels: [__address__]
        target_label: __param_target
      - target_label: __address__
        replacement: 172.19.155.133:9115

注意：10.165.94.31是被监控端ip，172.19.155.133是Blackbox_exporter

监控主机端口存活状态
  - job_name: 'prometheus_port_status'
    metrics_path: /probe
    params:
      module: [tcp_connect]
    static_configs:
      - targets: ['172.19.155.133:8765']

        target_label: instance
      - target_label: __address__
        replacement: 172.19.155.133:9115


监控网站状态

  - job_name: web_status
    metrics_path: /probe
    params:
      module: [http_2xx]
    static_configs:
      - targets: ['http://www.baidu.com']
