用扩展事件捕获死锁

一、打开 SSMS ， 找到 “扩展事件”->"会话"->“新建会话向导”：



二、会话名称为： Deadlock_Monitor



三、不使用模板



四、事件库文本框键入： deadlock  ,   将 xml_deadlock_report  加到右边



五、选择一些需要的字段， 不选择也没关系（因为我们只需要知道死锁是怎么造成的就可以了）



六、直接下一步



七、选择扩展事件文件保存位置



八、点击“脚本”， 查看。当然， 也可以直接点完成来创建事件。不过， 有了脚本下次可以一次性创建， 更方便。



CREATE EVENT SESSION [Deadlock_Monitor] ON SERVER
ADD EVENT sqlserver.xml_deadlock_report(
ACTION(sqlserver.database_id,sqlserver.database_name,sqlserver.plan_handle,sqlserver.sql_text,sqlserver.username))
ADD TARGET package0.event_file(SET filename=N'D:\Tools\DBA\EventLog\deadlock.xel',max_file_size=(20))
WITH (STARTUP_STATE=ON)
GO

八、验证是否有效：
窗口一：

USE AdventureWorks2014
GO
BEGIN TRAN
UPDATE Person.Address SET AddressLine1 = 'New address' WHERE AddressID = 20092
WAITFOR DELAY '0:0:10'
SELECT * FROM Person.Address WHERE AddressID = 20091

窗口二：
USE AdventureWorks2014
BEGIN TRAN
UPDATE Person.Address SET AddressLine1 = 'New address' WHERE AddressID = 20091
WAITFOR DELAY '0:0:10'
SELECT * FROM Person.Address WHERE AddressID = 20092

窗口二最后提示：
消息 1205，级别 13，状态 51，第 5 行

事务(进程 ID 67)与另一个进程被死锁在 锁 资源上，并且已被选作死锁牺牲品。请重新运行该事务。

最终显示的死锁就是非常清晰的了！
