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
二. sp_whoisactive
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。
其完整代码如下:
set quoted_identifier on;
set ansi_padding on;
set concat_null_yields_null on;
set ansi_warnings on;
set numeric_roundabort off;
set arithabort on;
go
if not exists (select * from information_schema.routines where routine_name = 'sp_whoisactive')
exec ('create proc dbo.sp_whoisactive as select ''stub version, to be replaced''')
go

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
