In IIS 7, I would click on "worker process" then "View Current Request" to see all the requests currently being executed.

In IIS 8, I do not see this option. Is there something I need to set up on IIS 8?
Edit: I tried running inetmgr as administrator as well.
There wasn't any UI hints, but was able to turn it on as a feature under server manager.
Server Manager -> Add Roles.
