[2] GUI achieve

(Occurs when the Transact-SQL statement is completed) based sql_statement_completed

And query_post_execution_showplan (occurs after executing SQL statements. This event returns the XML representation of the actual query plan. Using this incident could have serious performance overhead so should only be used in this event only a short time to solve a specific problem or monitor. )

　　(1) create a new session, the sql_statement_completed and query_post_execution_showplan events to elected

　　

 

　　(2) predicate screened duration greater than 3s and exclude system database, two events are so set

　　　　

　　(3) real-time monitoring, view the results

　　　　

　　(4) do modify, add global fields and event fields. The query_post_execution_showplan event plus the username global fields and databaseName

　　　　

 

 

 　　(5) View added after the results of field

【2】GUI实现

基于 sql_statement_completed（Transact-SQL 语句已完成时发生）

和 query_post_execution_showplan （在执行 SQL 语句后发生。此事件返回实际查询计划的 XML 表示形式。使用此事件可能带来严重的性能开销，所以只有在短时间内解决或监视特定问题时才应使用此事件。）

　　（1）新建会话，把sql_statement_completed 和 query_post_execution_showplan 事件给选上

　　

 

　　（2）谓词 筛选出持续时间大于3s的，并排除系统数据库，两个事件都这么设置

　　　　

　　（3）实时监控，查看结果

　　　　

　　（4）再做修改，加全局字段与事件字段。而query_post_execution_showplan事件加了username全局字段和databaseName

　　　　

 

 

 　　（5）查看加了字段之后的结果
