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证书状态澳门正版资料大全免费大全鬼谷子。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。
