HP WBEM Indications
Chapter 2 23
The abstract class CIM_Indication serves as the base class for all
Indication classes. A CIM Indication Provider registers with the CIM
Server to Generate indications of one or more classes.
A CIM Indication Provider translates the detection of an Event into a
CIM Indication and sends the Indication to the CIM Object Manager for
further processing and delivery.
Indication Subscription
An Indication Subscriber is a CIM Client that issues CIM Operation
requests to create instances of the CIM_IndicationSubscription class.
The Subscription Filter specifies what indications should be sent (i.e.
what events are of interest), and the Subscription Handler specifies
where and how (i.e. by what protocol) indications should be sent. The
CIM Indication Service coordinates the handling of subscriptions among
the Indication Providers.
A CIM Server receives and processes CIM Operation requests and
issues CIM Operation responses.
The CIM Indication Service is a component of the CIM Object
Manager. It is responsible for the processing of CIM Operations on the
classes in the CIM Subscription Schema.
Indication Processing
The CIM Indication Service is a component of the CIM Object Manager.
It processes each generated indication to determine to which indication
handlers, if any, the indication should be sent.
Indication Delivery
A CIM Indication Handler receives Indications, performs the mapping
between the internal representation of a CIM Indication and the desired
format and protocol, and sends the Indication to the designated
destination.
NOTE A CIM Server may support multiple indication handler interfaces.
