A DGE is the Data Gathering Engine. The DGE polls devices for various tests such as CPU and bandwidth utilization and aggregates the data that it gathers. Generally, a DGE is physically near the devices that it monitors. A DGE can typically monitor approximately 500 - 1,500 devices. See Disk Space Requirements for DGE Aggregation for sizing algorithms).
A DGE location is a collection of one or more DGEs that are automatically load balanced for provisioned tests. The DGEs within a single DGE Location are usually located in the same physical region, but they can be separate in some special situations. When you provision a device, you assign it to a DGE Location, not to an individual DGE. If there is more than one DGE at that location, Traverse automatically assigns the device to the least loaded DGE.
