When you are looking to see what apps are in your db and you want to update those apps, you may come across some apps you (sysadmin) did not know you had in your organization. You see the machine count next to the product/vendor but not an easy way to see the list. The only way to see this list is if you go back to monitoring and search for the application there.
It would be beneficial if the machine count was a hyperlink to the actual machine count list. I feel if that was hyperlinked, then this db scan would be seamless for sysadmins to verify what specific machines/collections had the application.
