如何获得SQL Server的总I/O统计与日期范围

Question

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

我得到的查询

-- 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 

我如何获得这一点，但这个时候我可以有时间过滤器？ 即

where 
xDate between Date1 and Date2 

？

@Note：

这是问题How to find out SQL Server table's read/write statistics with Date Filter?不同，因为这是总的，另一种是按表

你将不得不采取定期快照并比较不同时间才能够做什么你在问。
