环境

系统：CentOS 7.5

准备

• Blackbox exporter安装

配置Prometheus

• 修改配置

  # vim prometheus.yml
  scrape_configs:
    - job_name: 'TCP'
      metrics_path: /probe
      params:
        module: [tcp_connect]
      static_configs:
        - targets:
          - host1.domain.com:22
          - host2.domain.com:3306
      relabel_configs:
        - source_labels: [__address__]
          target_label: __param_target
        - source_labels: [__param_target]
          target_label: instance
        - target_label: __address__
          replacement: 127.0.0.1:9115
  

  127.0.0.1:9115是Blackbox exporter地址

• 重新加载配置

  # systemctl reload prometheus
