查詢通話記錄
概觀和存取
在您可充分利用 Log Analytics 以取得通訊服務記錄之前,必須先遵循在診斷設定中啟用記錄中所述的步驟。 啟用記錄和 Log Analytics 工作區之後,您就能存取許多實用的預設查詢套件,藉以協助您快速視覺化並瞭解記錄中可用的資料,如下所述。 透過 Log Analytics,您也可透過 Azure 監視器 Workbooks 存取更多通訊服務深入解析、建立自己查詢和 Workbook 的能力,並可取得對任何查詢的 Log Analytics 概觀。
存取
您可從 [通訊服務] 資源頁面開始存取查詢,然後按一下 [監視] 區段內左側導覽中的 [記錄]:
從這裡,您會看到強制回應畫面,其中包含通訊服務可用的所有預設查詢套件,以及瀏覽左側提供的查詢套件清單。
如果您關閉強制回應畫面,仍可瀏覽至各種查詢套件,並根據您在診斷設定中啟用的記錄和計量結構描述,直接存取資料表形式的資料。 在這裡,您可使用 KQL (Kusto) 根據資料建立自己的查詢。 若要深入瞭解如何使用、編輯和建立查詢,請參閱:Log Analytics 查詢
