介绍几种应用场景这个有空要试一下

blackbox_exporter源码阅读

网络探测监控的操作还有HTTPS DNS TCP ICMP SSH etc

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'
    relabel_configs:
      - 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']
        labels:
          instance: 'port_status'
          group: 'tcp'
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        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']
        labels:
          instance: user_status
          group: 'web'
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - target_label: __address__
        replacement: 172.19.155.133:9115
