get http://{hostname}/gtm-load-data/v1///
Use this action to fetch the load data for a resource instance. The URL format is the same as the POST action. The API returns either XML or JSON, depending on your Accept header. If both are specified, or there is no Accept header, the default is JSON. In this sample data, we're fetching load for a resource called connections in datacenter 100, in the example.akadns.net domain.
