一、域名过期时间监控
域名的监控通过domain_exporter来完成
domain_exporter：https://github.com/caarlos0/domain_exporter/releases
二、domain_exporter安装
2.1 源码安装方法
https://prometheus.io/download/
wget https://github.com/caarlos0/domain_exporter/releases/download/v1.20.0/domain_exporter_1.20.0_linux_amd64.tar.gz tar zxvf domain_exporter_1.20.0_linux_amd64.tar.gz mkdir /opt/prometheus -p mv domain_exporter_1.20.0_linux_amd64 /opt/prometheus/domain_exporter # 创建用户，并给文件夹授权 useradd -M -s /usr/sbin/nologin prometheus chown prometheus:prometheus -R /opt/prometheus #创建systemd服务 cat <<"EOF" >/etc/systemd/system/domain_exporter.service [Unit] Description=domain_exporter After=network.target [Service] Type=simple User=prometheus Group=prometheus ExecStart=/opt/prometheus/domain_exporter/domain_exporter Restart=on-failure [Install] WantedBy=multi-user.target EOF # 启动 systemctl daemon-reload systemctl start domain_exporter systemctl enable domain_exporter
2.2 docker安装方式
docker run -d --restart=always --name domain_exporter -p 9222:9222 caarlos0/domain_exporter
3.Prometheus设置
cd /data/docker-prometheus
cat >> prometheus/prometheus.yml <<"EOF"
- job_name: domain
#scrape_interval: 1h
scrape_interval: 15s
metrics_path: /probe
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- target_label: __address__
replacement: 192.168.10.100:9222 # domain_exporter address
static_configs:
- targets:
- qq.com
- baidu.cn

3.1 常用监控项目
domain_expiry_days 域名到期时间 domain_probe_success 域名检测状态
4.domain触发器(告警规则)
cat >> prometheus/rules/domain.yml <<"EOF"
groups:
- name: domain
rules:
- alert: 域名检测失败
expr: domain_probe_success == 0
for: 2h
labels:
severity: warning
annotations:

description: '{{ $labels.domain }}域名检测失败'
- alert: 域名过期
expr: domain_expiry_days < 30
for: 2h
labels:
severity: warning
annotations:
summary: '{{ $labels.instance }}'
description: '{{ $labels.domain }}将在30天后过期'
- alert: 域名过期
expr: domain_expiry_days < 5

EOF
重新加载配置：

4.grafana dashboard图形展示
https://grafana.com/grafana/dashboards/14605
id14605显示域名不正确，需要修改
找到右边的Column Styles，在找到“域名”这列，把instance修改为domain
