：接入Grafana警示（Grafana 8.0及以上版本）

Grafana配置

1. 登入Grafana控制台。
2. 建立Contact point。
   1. 在左側導覽列中，選擇Alerting > Contact points，然後單擊New contact point。
   2. 在Create contact point頁面中，配置如下參數。
      

      參數	說明
      Name	設定Contact point名稱。
      Contact point type	Contact point的類型，此處配置為webhook。
      Url	Contact point的URL，此處配置為您在Log Service中建立開放警示服務和應用後產生的介面資訊（完整URL）。如何擷取，請參見擷取介面資訊。

   3. 單擊Save contact point。
3. 為通知策略綁定Contact point。
   您可以通過修改通知策略的根策略或建立路由策略來綁定Contact point。此處以修改根策略為例。
   1. 單擊Notification policies。
   2. 在Root policy - default for all alerts地區，單擊Edit。
   3. 在Default contact point列表中選擇您在步驟2中建立的Contact Point。
      
   4. 單擊Save。
