Actually that view should be available in 10.5:
I've caught myself a few times where I was accidentally looking at the "Site" level as opposed to the "Server" level. That is, this particular view is only available to Server Administrators so you want to be sure that the "Manage All Sites" option has been selected so it's allowing you to see all the Server Admin views versus just the Site Admin views.
Of course, I should have checked there! Thank you Mark!
