Get Metrics

Monitorable, a GAT abstraction tagging an instance as being able to be monitored, has a function called GetMetrics. This is the starting point for most monitoring. Upon calling this function the caller is returned a List of Metric instances. You say: ``So, what is a Metric?'' A Metric is an abstraction which represents a measurable quantity within the monitoring system. So, a call to the function GetMetrics on a Monitorable is a means for the caller to obtain from the Monitorable a description of the various quantities which it allows to be monitored. If only it were this easy for Lance.
