An overview of experiment usage of the testbed as reported by the testbed controller in allocation of slivers (virtual machines) per groups represented in a Treemap graph where the area is proportional to the number of slivers per experiment. The data is refreshed from the testbed controller every 15 minutes.
Moving the pointer over slices shows details in number of slivers allocated to that experiment (not the actual usage of it). The pointer over a group (border) shows the aggregate numbers for that group.
