SQLDiag工具程式的使用
前言:SQLDiag是SQL Server內建的診斷收集共用程式,
[SQL Server 2005]
預設位置:C:\Program Files\Microsoft SQL Server\90\Tools\Binn\SQLDiag.exe
你可以在任何路徑下執行SQLDiag因為此路徑已被加到path系統變數,執行sqldiag -?或sqldiag /?即可顯示參數說明

SQL 2005的sqldiag搭配參數請使用正斜線"/"
SQLdiag
可以收集下列類型的診斷資訊:
Windows 效能記錄
Windows 事件記錄檔
SQL Server Profiler 追蹤
SQL Server 封鎖資訊
SQL Server 組態資訊
可以收集下列類型的診斷資訊:
Windows 效能記錄
Windows 事件記錄檔
SQL Server Profiler 追蹤
SQL Server 封鎖資訊
SQL Server 組態資訊
一般使用:
例如:
sqldiag /O C:\temp\sqldiag
(/O 指定輸出檔案的目錄)
最下方會出現
2008/07/01 00:34:42.82 SQLDIAG
Collection started. Press Ctrl+C to stop.表示正在收集中
在此時按下Ctrl+C即可停止收集 收集的資訊會儲存在指定的C:\temp\sqldiag\目錄下,其中數個log_xx.trc檔是從C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\LOG\路徑下所複製的
例如:
sqldiag /O C:\temp\sqldiag
(/O 指定輸出檔案的目錄)

進階收集: 修改並指定xml檔,來收集Performance Counter的資訊
[SQL Server 2000]
預設位置:C:\Program Files\Microsoft SQL Server\MSSQL\Binn\SQLDiag.exe
切換目錄到此位置後執行sqldiag -?或sqldiag /?即可顯示參數說明
SQL 2000的sqldiag搭配參數執行要使用"-"
例如: sqldiag -E -O c:\temp\sqldiag.log
(-O 指定輸出資訊到指定的檔案裡)
預設位置:C:\Program Files\Microsoft SQL Server\MSSQL\Binn\SQLDiag.exe
切換目錄到此位置後執行sqldiag -?或sqldiag /?即可顯示參數說明
SQL 2000的sqldiag搭配參數執行要使用"-"
例如: sqldiag -E -O c:\temp\sqldiag.log
(-O 指定輸出資訊到指定的檔案裡)
若要讓SQL 2000可以取得SQL Trace(*.trc)資料,可以利用下面[Sample Code]或KB281671文件範例SQL在master資料庫新增一個名為trace_blackbox的Stored Procedure
KB281671 INF: 預存程序來建立一個 SQL Server 2000 的 blackbox 追蹤
然後在排定時間執行trace_blackbox 1以啟動trace_blackbox,執行期間這個Instance所有連線的SQL Command都會記錄到C:\Program Files\Microsoft SQL Server\MSSQL\Data\blackbox開頭.trc,在必要的時間執行trace_blackbox 0以關閉trace_blackbox,而這些trc檔案都將會被sqldiag所複製並更名到指定的位置

[Caution]
若執行SQLDiag當時trace_blackbox還開著,檔案將無法複製所以SQLDiag.trc會是空的
