Prometheus+blackbox_exporter监控Linux主机端口

一、环境说明

172.16.38.246--->Prometheus
120.92.74.166--->blackbox_exporter(开启8080/8081端口)

二、目的

Prometheus监控120.92.74.166的8080和8081端口

三、安装blackbox_exporter

wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.16.0/blackbox_exporter-0.16.0.linux-amd64.tar.gz
tar xvf blackbox_exporter-0.16.0.linux-amd64.tar.gz
mv blackbox_exporter-0.16.0.linux-amd64 /usr/local/bin/blackbox_exporter
/usr/local/bin/blackbox_exporter/blackbox_exporter &

四、Prometheus添加如下配置文件

​​vim prometheus.yml​​

- job_name: 'port_status'
    metrics_path: /probe
    params:
      module: [tcp_connect]
    static_configs:
      - targets: ['120.92.74.166:8080','120.92.74.166:8081']
        labels:
          instance: 'port_status'
          group: 'tcp'
    relabel_configs:
      - source_labels: [__address__]
        target_label: __param_target
      - target_label: __address__
        replacement: 120.92.74.166:9115

./promtool check config prometheus.yml
systemctl restart prometheus.service

五、WEB验证

​​http://172.16.38.246:9090/targets​​​
这样就实现了对Linux主机端口的监控
