1. -----创建审核对象之前需要切换到master数据库
   
2. --USE [master]
   
3. --GO
   
4. --CREATE SERVER AUDIT MyAudit TO FILE(FILEPATH='D:\SqlAudits') --这里指定文件夹不能指定文件，生成文件都会保存在这个文件夹
   
5. --GO
   
6. --实际上，我们在创建审核对象的同时可以指定审核选项，下面是相关脚本
   
7. --把日志放在磁盘的好处是可以使用新增的TVF:sys.[fn_get_audit_file] 来过滤和排序审核数据，如果把审核数据保存在Windows 事件日志里查询起来非常麻烦
   
8. USE [master]
   
9. GO
   
10. CREATE SERVER AUDIT MyAudit TO FILE(
    
11. FILEPATH='D:\SqlAudits',
    
12. MAXSIZE=2GB,
    
13. MAX_ROLLOVER_FILES=12)
    
14. WITH (
    
15. ON_FAILURE=CONTINUE,
    
16. QUEUE_DELAY=1000);
    
17. ALTER SERVER AUDIT MyAudit WITH(STATE =ON)
    
18. --MAXSIZE：指明每个审核日志文件的最大大小是4GB
    
19. --MAX_ROLLOVER_FILES：指明滚动文件数目，类似于SQL ERRORLOG，达到多少个文件之后删除前面的历史文件，这里是6个文件
    
20. --ON_FAILURE：指明当审核数据发生错误时的操作，这里是继续进行审核，如果指定shutdown，那么将会shutdown整个实例
    
21. --queue_delay：指明审核数据写入的延迟时间，这里是1秒，最小值也是1秒，如果指定0表示是实时写入，当然性能也有一些影响
    
22. --STATE：指明启动审核功能，STATE这个选项不能跟其他选项共用，所以只能单独一句
    
23. --在修改审核选项的时候，需要先禁用审核，再开启审核
    
24. --ALTER SERVER AUDIT MyFileAudit WITH(STATE =OFF)
    
25. --ALTER SERVER AUDIT MyFileAudit WITH(QUEUE_DELAY =1000)
    
26. --ALTER SERVER AUDIT MyFileAudit WITH(STATE =ON)
    
27. 
    
28. 
    
29. USE [T_restore]
    
30. GO
    
31. CREATE DATABASE AUDIT SPECIFICATION CaptureDBActionToEventLog
    
32. FOR SERVER AUDIT MyAudit
    
33. ADD (database_object_change_group),
    
34. ADD (INSERT,UPDATE,DELETE ON schema::dbo BY PUBLIC)
    
35. WITH (STATE =ON)
    
36. --我们先在D盘创建sqldbaudits文件夹
    
37. --第一个操作组对数据库中所有对象的DDL语句create，alter，drop等进行记录
    
38. --第二个语句监视由任何public用户（也就是所有用户）对dbo架构的任何对象所做的DML操作
