global:
  resolve_timeout: 5m #處理超時時間，預設為5分鐘
  external_url: 'http://xxxxx:8893'
  
  smtp_from: 'xxx@qq.com'       # smtp_from：指定通知報警的郵箱
  smtp_smarthost: 'smtp.qq.com:25'        # smtp_smarthost: 使用email開啟服務配置
  smtp_auth_username: xxx@qq.com'    # smtp_auth_username：郵箱使用者名稱
  smtp_auth_password: xxxxxxxxxxxxj'    # 此處為郵箱授權碼

route:
  group_by: ['alertname', 'item']  # 傳入報警分組在一起的標籤，如item=測試和alertname=Disk的多個報警將批處理為單個組
  group_wait: 30s  # 這個引數設定了在傳送第一批警報之後，Alertmanager 等待新警報加入現有組的時間。此處 group_wait 被設定為 30 秒。如果在 30 秒內沒有新的警報加入組，那麼這個組的警報將被髮送出去。
  group_interval: 300s  # 傳送組警報的時間間隔
  repeat_interval: 4h  # 對同一個警報組的重複通知之間的時間間隔 對於email配置中，此項不可以設定過低，否則將會由於郵件傳送太多頻繁，被smtp伺服器拒絕
  receiver: 'email'   # 傳送警報的接收者的名稱，以下receivers name的名稱
  
       
# 定義模板
#templates:
#  - '/usr/local/alertmanager/template/*.tmpl'

receivers:

# 接收郵件的郵箱
- name: 'email'
  email_configs:
  - to: 'xxxxxxxx'

inhibit_rules: # 抑制規則
  - source_match:
      severity: 'critical'
    target_match:
      severity: 'warning'
    equal: ['alertname', 'dev', 'instance', 'prod']
