SYS.Stats.Global

Class SYS.Stats.Global Extends SYS.WSMon.wsResource [ System = 4 ]

This class represents system metrics captured for globals. Each property is a different metric. A class may be instantiated by calling the class method 'Sample', and then the current value of each property can be accessed.

For example: s ref=##class(SYS.Stats.Global).Sample() w ref.RefLocal ; display number of local global references System stats for Global activity
