There are three sets of tools in HIVE under the admin portal: Enterprise, Project and CMS. Enterprise contains an overview area, user statistics, Revit versions and Revit Add-ins:
Revit add-ins will also show what software tools have been installed on each machine, so if you want to look for things that should not be there, that is an option. You can also look to see if a plug-in was installed after sending a deployment through the network. Ideally that is a great tool for collaboration between BIM managers and IT to make sure software is installed correctly.
Model summaries can show file links, properties like worksets and phases, how many design options, views and families there are, and whether families are being used or just loaded into the project. There are also levels, room counts and space information all being tracked in a user interface that is project facing. Even to the point of having model warnings shown for the entire model selected.
Under the Revit content sub-menu, it shows how many families are loaded, most used and unused families, Revit categories loaded, family versions, largest families and can even drill down to which families are being used or loaded into which project models.
