重新启动Azure Data Studio之后，SQL Server Profiler扩展状态更改为“禁用或卸载”。您还可以在此处注意到SQL Server Profiler扩展处于预览状态，我们可能会在后续版本中获得进一步的增强。

We can launch the SQL Server Profiler from the command pallet. Click on the View->Command Pallet -> Profiler->New Profiler

我们可以从命令托盘启动SQL Server Profiler。单击查看->命令面板->探查器->新探查器

Alternatively, we can use the shortcut key Alt + P. It launches’ the create new profiler section’ as shown below.

或者，我们可以使用快捷键Alt +P。它将启动“创建新的探查器部分”，如下所示。

In this, we can define the session template from the drop-down list.

结论 (Conclusion)

SQL Server Profiler is a useful enhancement to Azure Data Studio. However, currently, in a preview state, we cannot define the custom template or events to capture the relevant data. We learned to use the SQL Server Profiler in this article. This extension might get further enhancements in an upcoming release.

SQL Server Profiler是对Azure Data Studio的有用增强。但是，当前，在预览状态下，我们无法定义自定义模板或事件来捕获相关数据。我们在本文中学习了使用SQL Server Profiler。此扩展可能会在即将发布的版本中得到进一步的增强。
