%Monitor.System.Servers

Class %Monitor.System.Servers Extends (%Monitor.System.Adaptor, %Monitor.System.Abstract) [ Inheritance = right, System = 4 ]

Monitor system metrics by ECP server.

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 metrics, which can have a significant impact on a busy system. Note that stopping ^PERFMON will also disable the sampling here.
