prometheus配置ping监测

vim prometheus.yml中添加如下内容
  - job_name: "主机网络监测"
    metrics_path: /probe
    params:
      module: [ping]
    file_sd_configs:
    - refresh_interval: 10s
      files:
      - "/usr/local/prometheus/ping_host/ping_status*.yml"
    relabel_configs:
    - source_labels: [__address__]
      regex: (.*)(:80)?
      target_label: __param_target
      replacement: ${1}
    - source_labels: [__param_target]
      target_label: instance
    - source_labels: [__param_target]
      regex: (.*)
      target_label: ping
      replacement: ${1}
    - source_labels: []
      regex: .*
      target_label: __address__
      replacement: 127.0.0.1:9115 #此处是black_exporter和prometgeus关联的地方

创建ping_status.yml文件

[root@codeversionforgitserver ping_host]# more  ping_status.yml
- targets: ['192.168.11.165','10.2.2.32','10.2.2.35','10.2.2.36','10.2.2.37','10.2.2.95','10.2.2.96','10.1.32.25','10.1.32

  labels:
    group: '移动门户-网络PING监控'
- targets: ['10.1.32.46','10.1.32.46']
  labels:
    group: 'TIM-网络PING监控'
- targets: ['10.1.32.59','10.1.32.70','10.1.32.66','10.1.32.67','10.1.32.61','10.1.32.62','10.1.32.63','10.1.32.64','10.1.

  labels:
    group: '门户PORTAL-网络PING监控' 
[root@codeversionforgitserver ping_host]# 

此时prometheus配置ping监测完成；
检查是否成功
访问prometheus

点击会出一个链接地址，访问此地址（注意&需要转义）通过配置文件可以很直接的看出Prometheus使用black_exporter作为代理使用black_exporter配置的module检测各个target的状态
[root@codeversionforgitserver ping_host]# curl http://codeversionforgitserver:9115/probe?module=ping\&target=10.1.32.142
