In IIS 7.0, managing worker processes has never been easier and can be done through both IIS Manager and through Appcmd. Thanks to the new core architecture, a request-based tracing feature is now built into IIS 7.0. You can now easily query current requests inside a particular worker process with a few mouse clicks in IIS Manager. Alternatively, you can simply use Appcmd to query the run-time status. Available details include the HTTP verb of the particular request, requested resource name, the processing state of the request, and the module that is currently processing the request.
Show all "spinners" in IIS:
C:\Windows\System32\inetsrv\appcmd.exe list request /time:"$>600000" /text:apppool.name
@echo off
echo --- this is requests with "spinning" time more than 10 minutes
pause
