CIM subscription mechanism

The CIM Event Model defines how CIM clients subscribe to receive indications as shown in Figure 19 and Figure 20. A CIM_IndicationFilter instance describes the set of conditions, a CIM_ListenerDestinationCIMXML instance defines the CIM listener and the communication protocol, that is, it describes the method and targets for distributing the indications. Finally, a CIM_IndicationSubscription association instance between the CIM_IndicationFilter instance and the CIM_ListenerDestinationCIMXML instance is used to subscribe for receiving these indications. The creation of this association instance activates the subscription.
