用Blackbox Exporter to Monitor web和端口

1.按照exporter

.wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.12.0/blackbox_exporter-0.12.0.linux-amd64.tar.gz

.tar -zxf blackbox_exporter-0.12..linux-amd64.tar.gz

.mv blackbox_exporter-0.14..linux-amd64 /usr/local/blackbox_exporter

../blackbox_exporter --version

2.vim /lib/systemd/system/blackbox_exporter.service   --  变成系统服务 netstat -anptu|grep 9115

[Unit]

Description=blackbox_exporter

After=network.target

[Service]

User=root

Type=simple

ExecStart=/usr/local/blackbox_exporter/blackbox_exporter --config.file=/usr/local/blackbox_exporter/blackbox.yml

Restart=on-failure

[Install]

WantedBy=multi-user.target

3.监控web和端口状态

  - job_name: web_status

    metrics_path: /probe

    params:

      module: [http_2xx]

    static_configs:

      - targets: ['http://192.168.1.49:8080/']

        labels:

          instance: web_status

          group: web

      - targets: ['https://www.baidu.com/']

        labels:

          instance: baidu_status

          group: baidu

    relabel_configs:

      - source_labels: [__address__]

        target_label: __param_target

      - target_label: __address__

        replacement: 127.0.0.1:

  - job_name: 'port_status'

    metrics_path: /probe

    params:

      module: [tcp_connect]

    static_configs:

      - targets: ['192.168.1.49:8080']

        labels:

          instance: 'port_status'

          group: 'tcp'

    relabel_configs:

      - source_labels: [__address__]

        target_label: __param_target

      - target_label: __address__

        replacement: 127.0.0.1:

6.监控端口和服务状态

  - alert: NodePortavaibility

    expr: probe_http_duration_seconds{} <  0.0000001

    for: 2m

    labels:

      severity: warning

    annotations:

      summary: "{{$labels.instance}}: port-不可以-使用"

      description: "{{$labels.instance}}: 端口响应时间大于 0.5us (当前值: {{ $value }})"

  - alert: Portisup

    expr: probe_success{} !=

    for: 2m

    labels:

      severity: warning

    annotations:

      summary: "{{$labels.instance}}: port-不可以-不等于1"

      description: "{{$labels.instance}}: 端口结果不等于1 (当前值: {{ $value }})"
