HP WBEM indications
In a network where several clients and resources are managed, certain events might occur. These
events, irrespective of nature or criticality, must be reported so that appropriate action is taken.
In this network, you can receive a notification from HP WBEM Services when an event occurs. For
example, if you want to know about errors in a disk write operation, it can be configured as an
event. Other examples include authentication attempts that fail, or even mouse clicks.
When events occur in your environment, HP WBEM Services reports the event as an indication.
Therefore, an indication is the representation of the occurrence of an event.
The abstract class CIM_Indication serves as the base class for all the Indication classes in
HP WBEM Services. 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.
Any indication from HP WBEM Services includes the following components:
• “Indication Subscription” (page 12)
• “Indication Processing” (page 12)
• “Indication Delivery” (page 12)
• “Indication Consumption” (page 13)
Indication Subscription
An Indication Subscriber is a CIM client that issues the CIM operation requests to create instances
of the CIM_IndicationSubscription class.
An Indication Subscription consists of an Instance, a Filter, and a Handler. The Instance is the
Subscription; the Filter determines the Indications that must be sent; and the Handler specifies
where these indications are to be sent and using which protocol.
The CIM Indication Service coordinates the handling of subscriptions among the Indication Providers.
The CIM Server receives and processes CIM operation requests and issues the CIM operation
responses. The CIM Indication Service is a component of the CIM Object Manager and is
responsible for processing 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 which indication handlers, if any, the indication must be sent to.
Indication Delivery
A CIM Indication Handler receives indications, and then performs a mapping between the internal
representation of a CIM Indication and the desired format and protocol. After the mapping is
complete, the CIM Indication Handler sends the indication to the designated destination. The CIM
Server supports multiple indication handler interfaces.
A CIM-XML Indication Handler, functioning as a CIM Client, uses the DMTF CIM-XML protocol to
send an indication to each specified destination.
Indication Listener
When the CIM Server acts as a CIM listener, the CIM Server functions as an HTTP server to receive
indications as CIM Export Messages.
