使用存储过程代替SQL SERVER Profilter进行跟踪
进行数据跟踪会影响数据库服务器的性能,为了尽量减少这方面的影响。使用存储过程也可以进行跟踪,并将结果输出到磁盘文件上,其性能消耗要比SQL SERVER Profilter要小很多。
采用T-SQL代替SQL SERVER Profilter进行跟踪的具体实现方法如下:
1、在master数据库中创建sp_perfworkload_trace_start存储过程

SET NOCOUNT ON;
USE master;
GO
IF OBJECT_ID('dbo.sp_perfworkload_trace_start') IS NOT NULL
DROP PROC dbo.sp_perfworkload_trace_start;

@tracefile AS NVARCHAR(254),
@traceid AS INT OUTPUT
AS
-- Create a Queue
DECLARE @rc AS INT;
DECLARE @maxfilesize AS BIGINT;
SET @maxfilesize = 5;
EXEC @rc = sp_trace_create @traceid OUTPUT, 0, @tracefile, @maxfilesize, NULL
IF (@rc != 0) GOTO error;
-- Client side File and Table cannot be scripted
-- Set the events
DECLARE @on AS BIT;
SET @on = 1;

+ ', Trace File: ''' + @tracefile + '''';
GOTO finish;
error:
PRINT 'Error Code: ' + CAST(@rc AS VARCHAR(10));
finish:
GO
2、在需要跟踪的数据库中执行如下SQL,设置跟踪的数据和输出路径并开始跟踪:
DECLARE @dbid AS INT, @traceid AS INT;
SET @dbid = DB_ID();
EXEC dbo.sp_perfworkload_trace_start
@dbid = @dbid,
@tracefile = 'c:\20131212',
@traceid = @traceid OUTPUT;
SET @dbid = DB_ID();
EXEC dbo.sp_perfworkload_trace_start
@dbid = @dbid,
@tracefile = 'c:\20131212',
@traceid = @traceid OUTPUT;
3、需要结束跟踪时运行如下代码,最后会生成.trc格式的文件:
EXEC sp_trace_setstatus 2, 0;
EXEC sp_trace_setstatus 2, 2;
EXEC sp_trace_setstatus 2, 2;
4、跟踪文件可以直接使用TSQL语句查询出来,也可以复制到其它机器上用SQL SERVER Profilter打开进行查看,或者将数据加载到表中进行分析:
SELECT * FROM sys.fn_trace_gettable('c:\2013121201.trc', NULL) AS t ORDER BY StartTime
