How to create a drilldown
You may have used the Drilldown option in SquaredUp v2 to set your own dashboard as the drilldown for users to see when they click on an object or group, instead of seeing the default and often unconfigurable SquaredUp page.
In SquaredUp v4 you can create a new perspective for users to see when they 'drilldown' on an object. SquaredUp v4 uses the concept of Total Dashboard Architecture (TDA) to make every page configurable, and perspectives (see What is a perspective?) to show several different views of an object, often each designed for a different audience. In SquaredUp v2 you had a single page showing a generic object view, for example all the information about a server. You now have several pages, called perspectives, each with a different focus on that object. For example, a SQL server will have a SQL perspective, as well as Memory, Disk, and Performance perspectives.
You can then drag your new perspective to the left of the perspectives ribbon so it becomes the default perspective seen.
