View resource usage at each site in IIS

Many administrators, especially virtual hosts, may have encountered 100% of IIS cpu, but don't know which website resources are occupied. Here is a way to check the resource usage of each web site. Not recommended, just use 1 when the problem occurs, set each site as a separate process to open the IIS site properties -- home directory -- change the application protection to high open task manager view the process you will see more Some dllhost.exe processes and their resource usage These are the processes of each web site, but now I don't know which web site uses the process 2, the dllhost.exe process corresponding to the web site opens the component management --- component service -- Computer -- My computer -- com+ application is here, we can see something like IIS-{domain.com//Root}, it can't be seen without setting it as a stand-alone process. This is the web site in IIS. Select the status view on the toolbar and you will see a name like this Running PIDIIS-{down.789game.com//Root} is 1688 where PID is the dll value of dllhost.exe in task management. Now know the dllhost.exe process used by each web site, and in the task manager again You can know the resources occupied by dllhost.exe, then you should know that the website is not working properly!
