一.常见简便的方式
通常，DBA使用sp_who和sp_who2系统存储过程或活动监视器来查看SQL实例中的当前会话、用户和进程。 我们还可以从这些过程中确定阻塞会话和活动会话。
1.1. Sp_who 如下：
1.2 Sp_who2 如下:
1.3 通过SQL Server活动监视器（SQL Server Activity Monitor）
进程窗格如下
这些过程没有提供太多有用的信息，例如等待信息，执行计划，当前运行的语句，持续时间。 现在，让我介绍另一个有用的存储过程sp_WhoIsActive，以获取SQL Server用户进程的即时视图。 它由Microsoft MVP Adam Machanic开发 。 我们可以从SQL Server 2005开始使用此存储过程。 您可以参考whoisactive的官方文档。 它从各种DMV收集数据，并以表格格式显示信息。
这是一个自定义存储过程。 我们可以从GitHub下载最新版本。 当前版本是11.35。 打开URL并下载其ZIP版本。

执行存储过程，结果输出如下:
3.指定特殊参数
此外，我们可以通过指定参数获取更多的运行信息
3.1 @find_block_leaders
可以将@find_block_leaders参数的值设置为1，然后对blocked_session_count列的结果进行排序，以检查潜在客户阻止程序和被阻止的会话。
EXEC sp_WhoIsActive
@find_block_leaders = 1,
@sort_order = "[blocked_session_count] DESC"
在输出结果中，我们看到session-id 58是线索阻止程序，它阻止了输出表中下面列出的2个会话。
3.2 @get_plans
指定参数@ get_plans = 1，能得到它的执行计划，输出中包含带有XML执行计划的附加列。
EXEC sp_WhoIsActive @get_plans = 1;
单击查询计划，您可以看到查询执行计划。
3.3 @get_locks
使用此参数获取XML代码段，以获取有关在SQL Server会话中持有的锁的详细信息
3.4 @get_additional_info
通过@get_additional_info 参数可以查看 可能性能性能的several session parameters
EXEC sp_WhoIsActive
@get_additional_info = 1
