** DEPRECATED **. This class has been deprecated for performance issues, and will no longer collect SystemMetrics.
This class, and others that inherit from %Monitor.System.Abstract, provides an object API to the same system metrics as the ^PERFMON utility. Instantiating this class also starts the collection of ^PERFMON system level metrics, which can have a significant impact on a busy system. Note that stopping ^PERFMON will also disable the sampling here.
Properties are inherited from AbstractMetrics and AbstractGlobals.
