在Prometheus中设置SSL证书过期告警并通过Telegram发送通知,可以结合Prometheus的Alertmanager来完成。首先,你需要创建一个Prometheus的规则文件(`.yaml`或`.cfg`),定义一个监控检查去检测目标URL的SSL证书状态。例如:
```yaml
groups:
- name: ssl_certificate_alerts
rules:
- alert: SSLCertificateExpirationWarning
expr: cert_expiration_seconds({service="your_service", instance="your_instance"}) < (now() - 3600) # 一小时内过期
for: 1h # 警告持续一分钟
labels:
severity: warning
annotations:
summary: 'SSL Certificate for {{ $labels.service }} will expire soon'
description: 'The SSL certificate of {{ $labels.service }} at {{ $labels.instance }} is about to expire in less than an hour.'
runbook: 'Update the certificate immediately'
```
然后,在Alertmanager配置中添加一个接收器,指定将警告信息推送到Telegram:
```yaml
receivers:
- name: telegram_notifier
webhook_configs:
- url: "https://api.telegram.org/bot<YOUR_BOT_TOKEN>/sendMessage"
send_resolved: true
http_method: POST
headers:
Content-Type: application/json
route:
group_by: [alertname]
receiver: telegram_notifier
```
确保替换上述配置中的`your_service`, `your_instance`, 和`YOUR_BOT_TOKEN`为你实际的服务名、实例名以及Telegram Bot API token。
当Prometheus检测到SSL证书即将过期,它会触发Alertmanager,后者再通过Webhook将警告消息发送到预设的Telegram群组或个人账户。
