Email#

Alertmanager 内置 email_configs，适合低频、审计类、非实时告警。

1. API / Protocol#

Email 使用 SMTP。

https://prometheus.io/docs/alerting/latest/configuration/#email_config

2. Alertmanager Config#

global:
  smtp_smarthost: smtp.example.com:587
  smtp_from: alertmanager@example.com
  smtp_auth_username: alertmanager@example.com
  smtp_auth_password: ${SMTP_PASSWORD}
  smtp_require_tls: true

route:
  receiver: email-platform

receivers:
  - name: email-platform
    email_configs:
      - to: platform@example.com
        send_resolved: true
        headers:
          subject: '{{ template "alert.title" . }}'
        html: '{{ template "alert.text" . }}'

3. Notes#

Best Practice:
    Email 不适合强实时告警
    用于日报、审计、低优先级告警更合适
    SMTP password 使用 Secret 管理
