An indication is the active representation of the occurrence
of an event. Indications are classes that have the indication qualifier
applied. Since indications are types of classes, they can have properties
and methods, and can be arranged in a hierarchy. Instances of an
indication are transient and can not be obtained by using CIM Operations,
such as getInstance() or enumerateInstances(). Indications can only
be received by subscribing to them.
There are two types of indications:
-
Classes - class creation, deletion and modification
-
Instances - instance creation, deletion, modification,
method invocation and read access
-
Process Indications - alert notifications associated
with objects that may or may not be completely modeled in CIM
or do not correspond to a simple life cycle event; like low-level
instrumentation alerts, DMI alerts, SNMP traps and TMN events
A Subscription is expressed by the creation
of an IndicationSubscription association instance that references
an IndicationFilter (a Filter) instance, and an IndicationHandler
(a Handler) instance. A Filter contains the query that selects
an Indication class or classes. The size and complexity of the result
delivered to the subscriber is dictated by the query.

Model, see the CIM Event White Paper and UML Diagram.
