# Alertmanager 告警通知配置
#
# ⚠️ TODO（上线前必填）：将 receivers.default.webhook_configs 替换为真实通知渠道：
#   - 钉钉机器人：https://oapi.dingtalk.com/robot/send?access_token=XXX
#   - 企业微信群机器人：https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=XXX
#   - 邮件 SMTP：配置 global.smtp_* + email_configs
#
# 当前为占位 webhook（指向无效端点），alertmanager 会启动但告警 POST 失败记日志。
# PP-04 MVP 目的：先打通 prometheus → alertmanager 链路，渠道上线前填。

global:
  resolve_timeout: 5m

# 路由：按 alertname + service 分组，先 SEV-1（critical）走即时通知
route:
  receiver: "default"
  group_by: ["alertname", "service"]
  group_wait: 30s
  group_interval: 5m
  repeat_interval: 4h
  routes:
    # SEV-1 关键告警（DB 宕机/5xx 飙升/Redis 不可达）立即通知，5 分钟重复
    - matchers:
        - severity = "critical"
      receiver: "default"
      group_wait: 0s
      repeat_interval: 5m

receivers:
  - name: "default"
    # 占位：上线前替换为真实 webhook
    webhook_configs:
      - url: "http://placeholder.invalid/alert"
        send_resolved: true
