Abstract: In a method of generating governing metrics, a high-level goal to be met in a provisioned system is identified. In addition, a low-level governing policy designed to facilitate achievement of the high-level goal is selected and properties relating to the selected low-level governing policy are identified. The identified properties are formulated to define governing metrics relevant to the selected low-level governing policy and the formulated governing metrics are outputted. The formulated governing metrics are configured to be used in at least one of evaluating and controlling resource provisioning in the provisioned system.
