w3wp.exe进程与应用程序池的对应关系

https://blogs.msdn.microsoft.com/friis/2009/10/22/which-w3wp-exe-pid-corresponds-to-which-application-pool/

 

Navigate to the folder where appcmd is located and run the following command: 

appcmd list wp

this will list all the instances of the w3wp.exe process (worker process) that are present on your server with their respective PIDs and application pools.

Other nice commands are 

appcmd list sites 

and

 appcmd list appPools 

to list the web sites that are present on the server and the application pools on your IIS server.
