Prometheus+BlackBox-Exporter实现端口监控

Blackbox-Exporter添加Basicauth（非必要）

FROM prom/blackbox-exporter:v0.25.0
COPY password.yml /etc/blackbox_exporter/
EXPOSE 9115
ENTRYPOINT  [ "/bin/blackbox_exporter" ]
CMD         [ "--config.file=/etc/blackbox_exporter/config.yml","--web.config.file=/etc/blackbox_exporter/password.yml" ]

##构建镜像
docker build -t blackbox-exporter-s:v0.25.0 .
##运行容器
docker run -dit --network=host -v blackbox_exporter:/etc/blackbox_exporter/ --restart=always --name=blackbox-exporter-s blackbox-exporter-s:v0.25.0

调整配置

#1、默认不需要对Blackbox的配置文件进行修改

#2、监控目标端口，修改prometheus.yml即可。以下为示例：


  - job_name: '端口监控'
    basic_auth:
      username: abc
      password: 123
    metrics_path: /probe
    params:
      module: [tcp_connect]  ## 和Blackbox配置文件中的模块名对应
    static_configs:
      - targets: [10.1.1.101:9090]
        labels:   ## 标签可按照实际情况添加
          name: 'prometheus '
          ip: 10.1.1.101
          port：9090
          
      - targets: [10.1.1.101:3000]
        labels:
          name: 'grafana'
          ip: 10.1.1.101
          port：3000
          
      - targets: [10.1.1.101:9093]
        labels:
          name: 'alertmanager'
          ip: 10.1.1.101
          port：9093
          
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - source_labels: [__param_target]
        target_label: instance        # 把target重赋一个label，value为任意
      - target_label: __address__
        replacement: 10.1.1.101:9115  # 修改为blackbox-exporter的地址
