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。
