Metric Definition
A metric definition is an instance that contains all the information a metric source needs in order to extract a value (reading) for a specific metric.
The metric definition has an ID which uniquely identifies the metric to a metric source. The ID must not include anything that ties that ID to a specific metric source. The same ID can be given to different metric sources, and each metric source will return a different value of the metric.
A specific instance of a metric definition can be associated with a metric source via the metric source address.
