如何獲得SQL Server的總I/O統計與日期範圍

Question

從鏈接： http://www.databasejournal.com/features/mssql/article.php/2244381/Examining-SQL-Servers-IO-Statistics.htm

我得到的查詢

-- Take a look at raw I/O Statistics 
SELECT @@TOTAL_READ [Total Reads] 
    , @@TOTAL_WRITE as [Total Writes] 
    , CAST(@@IO_BUSY as FLOAT) * @@TIMETICKS/1000000.0 as [IO Sec] 
GO 

(Results) 

Total Reads Total Writes IO Sec 
----------- ------------ ----------- 
     85336  322109  25.375 

我如何獲得這一點，但這個時候我可以有時間過濾器？ 即

where 
xDate between Date1 and Date2 

？

@Note：

這是問題How to find out SQL Server table's read/write statistics with Date Filter?不同，因爲這是總的，另一種是按表

你將不得不採取定期快照並比較不同時間才能夠做什麼你在問。
