Indication Generation
You can receive a notification from WBEM when an Event happens. An
Event is the occurrence of a phenomenon of interest. An Event can be
defined to indicate, for example, the occurrence of a disk write error, a
failed authentication attempt, or even a mouse click.
An Indication is the representation of the occurrence of an Event.
