网络监控是运维工作之一，如何搭建高效可扩展的可视化网络监控成为运维工程师的一项重要技能，此篇文章讲介绍如何快速使用搭建一个网络质量可视化平台。

1.Prometheus 与Blackbox_exporter黑盒监测ICMP

1.1docker部署prometheus

docker run -p 9090:9090  -v /tmp/prometheus.yml:/etc/prometheus/prometheus.yml     prom/prometheus

#下载并解压blackbox_exporter黑盒探针压缩文件
wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.16.0/blackbox_exporter-0.16.0.linux-amd64.tar.gz
tar -zxvf blackbox_exporter-0.16.0.linux-amd64.tar.gz
cd blackbox_exporter-0.16.0.linux-amd64

#blackbox.yml文件如下
modules:
  http_2xx:
    prober: http
  http_post_2xx:
    prober: http
    http:
      method: POST
  tcp_connect:
    prober: tcp
  pop3s_banner:
    prober: tcp
    tcp:
      query_response:
      - expect: "^+OK"
      tls: true
      tls_config:
        insecure_skip_verify: false
  ssh_banner:
    prober: tcp
    tcp:
      query_response:
      - expect: "^SSH-2.0-"
  irc_banner:
    prober: tcp
    tcp:
      query_response:
      - send: "NICK prober"
      - send: "USER prober prober prober :prober"
      - expect: "PING :([^ ]+)"
        send: "PONG ${1}"
      - expect: "^:[^ ]+ 001"
  icmp:
    prober: icmp
    -------------------------
#启动黑盒探针
./blackbox_exporter --config.file="blackbox.yml" --log.level=error  &

1.2 配置prometheus

scrape_configs:
  - job_name: 'blackboxi_icmp'
    metrics_path: /probe
    scrape_interval: 5s
    params:
      module: [icmp]
    static_configs:
      - targets:
         - IP1
         - IP2
         - IP3
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance
      - target_label: __address__
        #blackbox exporter 所在节点
        replacement: 172.17.0.1:9115

重启prometheus 的docker容器使其生效

下载grafana并添加数据源

docker run -d --name=grafana -p 3000:3000 grafana/grafana

 

最后导入面板的json文件

https://grafana.com/grafana/dashboards/7587这里有现成的面板模板

 

导入后就能看到监控IP的延时数据了
