CddMetricPriority
This textual convention defines a priority level of a metric type. The priority is used by the Distributed Director to determine the order in which metrics are considered for selecting a server. The less the value, the higher the priority is. For example, the DRP external metric's priority has the value '1' and the random metric's priority has the value '2'. All potential server's DRP external metrics are compared first. If multiple servers have the same metric value, the random metrics would be compared next. If multiple metric types have the same priority value, the metrics are added to obtain a composite metric. If a metric's priority has the value of '0', the metric is not considered to determine the best server.
