For realizing the present invention, the embodiment of the invention newly-increased subclass (internal class) in existing standard is transmitted in CIM server inside the event that the CIM server receives with realization.In concrete realization, need to improve existing CIM server architecture.Referring to Fig. 1, the CIM server that the embodiment of the invention provides is expanded the agreement that its forward process interface IndicationDeliveryHandler 103 supports, increase the Internal protocol-identifier of supporting the event that reports is given to CIM server internal module, namely in forward process interface IndicationDeliveryHandler 103, increase inner forward process (InternalIndicationDeliveryHandler) interface.And.And increase WBEM monitors interface, and make WBEM monitoring interface can identify the internal module of the registering CIM server that carries the Internal protocol-identifier as the request of the receiving terminal of event, and provide the interface of event forwarding to the internal module of CIM server for receiving terminal according to this Internal protocol-identifier, be that inner WBEM monitors interface, and the inside WBEM that is provided by it to monitor interface be as the distribution of the internal module of the CIM server of the receiving terminal of the event objective attribute target attribute sign as described receiving terminal, such as port numbers.So that be transmitted to the event of CIM server internal module by the needs of InternalIndicationDeliveryHandler interface reception CIMOM transmission, and this event is sent to inner WBEM monitor interface, the inside WBEM that monitors interface by WBEM monitors the receiving terminal (such as adaptation module b) that reported event that the objective attribute target attribute sign (such as port numbers) of the described receiving terminal of interface appointment receives Common Information Model Object Manager is transmitted to CIM server inside.Certainly, InternalIndicationDeliveryHandler interface and inner WBEM monitoring interface can also close and be made as an interface, when closing when being made as an interface, monitor interface by inner WBEM and receive the needs that CIMOM sends and be transmitted to the event of CIM server internal module, and the objective attribute target attribute of monitoring the described receiving terminal of interface appointment by inner WBEM identifies the receiving terminal (such as adaptation module b) that reported event that (such as port numbers) receive Common Information Model Object Manager is transmitted to CIM server inside
Concrete, the embodiment of the invention is to be implemented in CIM server inside event forwarding is seen also Fig. 4 to the interface of CIM Server Extension, at forward process interface IndicationDeliveryHandler expanding internal forward process interface InternalIndicationDeliveryHandler, make it when the forward process interface receives the event that need to be forwarded to CIM server internal module, this event be offered inner forward process interface and process.WBEM is monitored interface expand to increase inner WBEM monitoring interface.Make inner WBEM monitor interface and receive application with the request as receiving terminal of the internal module of CIM server, and be the receiving terminal distribution objective attribute target attribute sign (such as port numbers) of the internal module conduct of CIM server, and the reference information of storing received end and port numbers, and receive the event that inner forward process interface sends over, and according to reference information and the port numbers of the receiving terminal of storing event is sent to receiving terminal.
In addition, the embodiment of the invention has also increased the disposal ability of CIM server, makes its internal module as the CIM server of the receiving terminal of event (such as adaptation module etc.) have the ability of processing the event that receives.The content that the concrete ability of processing the event that receives comprises can be with reference to the ability of the CIM client process event of existing reception event (such as the various events that receive of statistics, various alarm events are analyzed and processing etc.) and can carry out follow-up expansion, the embodiment of the invention is not describing in detail at this.
The method flow diagram that Fig. 2 transmits for the realization event that embodiments of the invention provide is applied to comprise the steps: in the Common Information Model CIM server
Step 201, CIM Object Manager CIMOM receive the request of the receiving terminal of definition event, carry the objective attribute target attribute sign as described receiving terminal in the request of described definition event receiving terminal, and described receiving terminal are the sign of the internal module in the CIM server; CIMOM is according to the described receiving terminal that identifies the definition event as the objective attribute target attribute of described receiving terminal;
Concrete, after CIMOM receives the request of receiving terminal of definition event, the receiving terminal that carries in the request according to the receiving terminal of described definition event is that the sign (such as Internal) of the internal module in the CIM server creates the inner CIM_ListenerDestinationInternal of monitoring of CIM example, and the objective attribute target attribute sign of giving the described described receiving terminal that distributes for described receiving terminal for the objective attribute target attribute of described CIM_ListenerDestinationInternal example, such as port numbers etc.
In embodiments of the present invention, the implication of the example in example instance and the CIM system management is identical, all refers to process the object of event, model.In the CIM_ListenerDestinationInternal example, Internal represents the agreement of this example support or the attribute of this example.The CIM_ListenerDestinationInternal example is used for the internal module of the CIM server of sign monitoring or the event of processing, and its objective attribute target attribute is endowed the port numbers of distributing for described receiving terminal (being the internal module that the CIM service is cried).Usually, one be used for to receive and the internal module of the CIM server of the event of processing corresponding to a CIM_ListenerDestinationInternal example.
Step 202, described CIMOM receive the request of the example that creates the indication filter, and receive filtercondition and the storage of event by the example of described indication filter;
Concrete, CIMOM receives the request that creates the CIM_IndicationFilter example, the relevant information that comprises Filter in this request, the characteristic of the event that receives such as needs (person's that comprises the reporting events information and/or event type etc.), described CIMOM stores the relevant information (being filtercondition) of described Filter.The request that is specifically as follows according to the establishment CIM_IndicationFilter example that receives creates the CIM_IndicationFilter example, and this CIM_IndicationFilter example is used for match event and whether meets filtercondition.
Step 203, described CIMOM receive event subscription requests, it is related that described event subscription requests is used to described filtercondition and receiving terminal to set up, so that after the event that CIMOM receives, determine that according to the filtercondition of described storage described event needs send to described receiving terminal, the objective attribute target attribute sign by described receiving terminal sends to described receiving terminal with event.
Concrete, the transmitting terminal of two requests is crossed createInstance (instance of CIM_IndicationSubscription) with the object path information exchange of the object path information of the ListenerDestinationInternal example that receives and CIM_IndicationFilter example and is sent to CIMOM in the forwarding step 201 and 202, CIMOM creates the CIM_IndicationSubscription example, with the related information of the object path information of the object path information of setting up described ListenerDestinationInternal example and CIM_IndicationFilter example.Also can be understood as the CIM_IndicationSubscription example that creates by CIMOM with the object path information of ListenerDestinationInternal example and the object path information corresponding stored of CIM_IndicationFilter example.
After CIMOM receives event, CIMOM determines that the event of receiving satisfies the filtercondition of storage, and according to the described filtercondition of corresponding stored as the object path information of CIM_IndicationFilter example corresponding as described in the object path information of receiving terminal such as ListenerDestinationInternal example determine that the forward process interface is inner forward process interface, namely among the figure one " InternalIndicationDeliveryHandler " interface.By the InternalIndicationDeliveryHandler interface event is sent to the inside WBEM corresponding with the receiving terminal objective attribute target attribute and monitor interface, and monitor interface by inner WBEM and according to the objective attribute target attribute sign of receiving terminal event is sent to described receiving terminal.
The embodiment of the invention can receive the event that Common Information Model Object Manager CIMOM transmits by InternalIndicationDeliveryHandler interface and InternalWBEMListener interface.Concrete, InternalIndicationDeliveryHandler interface and InternalWBEMListener interface close and are made as an interface.After CIMOM receives event, CIMOM determines that the event of receiving satisfies the filtercondition of storage, and according to the described filtercondition of corresponding stored as the object path information of CIM_IndicationFilter example corresponding as described in the inner WBEM of object path information of receiving terminal such as ListenerDestinationl nternal example monitor interface, and monitor interface by inner WBEM and according to the objective attribute target attribute sign of receiving terminal event sent to described receiving terminal.
Can be known by said method, by the function of CIM server is expanded, can identify its protocol-identifier and be the request of inner (being internal), and process for this type of request.Thereby can define internal module in the CIM server as the receiving terminal of event, so that the internal module in the CIM server can be processed event.Owing to be that internal module in the CIM server is as the receiving terminal of event, therefore, the CIM server does not need by existing event forwarding to be changed the event of transmitting to the method for the CIM client outside the CIM server by the agreement of CIM client support, and the event after will changing sends to corresponding client.Thereby alleviate the CIM server to the protocol conversion amount of event forwarding, raise the efficiency.
In addition, carrying out the inner event of transmitting for need can be that computer is by each managed element of guard system, each managed element such as unified communication system, such as sms center, the note subsystem, unified communication system, the alarm event that reports by its corresponding adaptation module, it also can be the variety of event that CIM Object Management group phase CIMOM produces, increase, modification, deletion, the method call of the example of managing such as CIMOM, and the establishment of class, modification, deletion can produce corresponding life cycle event.
In embodiments of the present invention, can be that the event transmitting terminal is (such as a) adaptation module (such as the adaptation module b among Fig. 1) corresponding to tension management network element (being assumed to be the note subsystem) of corresponding managed element (being assumed to be sms center) of the adaptation module among Fig. 1 as the internal module of the CIM server of event receiving terminal.Therefore, if having realized event transmits in the inside of CIM server, the event forwarding that then adaptation module a can be reported is processed to adaptation module b, thereby make things convenient for adaptation module corresponding to tension management network element that the state of lower floor's managed network element (event that reports by its corresponding adaptation module) is monitored and processed, more convenient manages computer management system.
Fig. 3 is the flow chart of the event forwarding that carries out as managed object for unified communication system.This unified communication system is corresponding to the managed element of three levels, be respectively sms center (ME1), note subsystem (ME2), unified communication system (ME3), the adaptation module that each managed element is corresponding (provider) is respectively the alarm event of ME1Provider, ME2Provider, ME3Provider.ME1 and processes at ME2Provider, ME2Provider need to subscribe to the event of ME1, and the query attribute of the CIM_lndicationFilter example that creates for ME2Provider can following assignment:
“Select＊from?CIM_AlertIndication?where?AlertingManagedElement＝‘ME1’”，
Wherein ' the object path (CIM Object Path is referring to DMTF standard text DSP0004CIM Infrastructure Specification) of ME1 ' expression ME1.
Equally, the ME3 layer need to be subscribed to the event of ME2, and the query attribute of the CIM_Indication Filter example that creates for ME2Provider accordingly can following assignment:
“Select＊from?CIM_AlertIndication?where?AlertingManagedElement＝‘ME2’”
To sum up, in order to make the alarm event after this layer processing can be subscribed in the upper strata, need to revise " AlertingManaged Element " attribute of alarm event.Process the alarm event of ME1 such as ME2Provider after, with this event " AlertingManagedElement " attribute assignment be ' ME2 ', to make things convenient for the ME3Provider subscription.
Simultaneously, in order to record alarm event in the processing procedure of different levels, in the CIM_Alertlndication subclass, increase attribute, as shown in Figure 6.In embodiments of the present invention, at AltertingMETrace string[] in the path address of record note subsystem.
Concrete, the schematic flow sheet of the message subsystem that provides embodiment illustrated in fig. 3 and converged communication system receiving alarm event is provided.
The CIM adaptation module (ME2Provider) of step 301, note subsystem is at first obtained inner WBEM by WBEMListenerFactory (WBEM monitors interface) and is monitored interface.
Concrete, WBEMlistenerfactory receives ME2 and obtains inner WBEM monitoring interface (getListener (" Internal "): WBEMListener, wherein: WBEMListener represents to return a WBEMListener example) request, wherein " Internal " expression receiving terminal is the sign (mode of also namely transmitting is for transmitting in CIM server inside) of the internal module of CIM server.WBEMlistenerfactory returns the InternalWBEMListener interface, so that ME2Provider can be registered as oneself the receiving terminal of event, sends to receiving terminal thereby cause CIMOM event can be monitored interface by inner WBEM.
Step 302, ME2Provider monitor interface (internalWBEMListener) application port numbers (being the objective attribute target attribute sign of receiving terminal) to inner WBEM, oneself is registered as event receiving terminal corresponding to this port numbers, be addListener (this, 0, null): the request of port (: Port represents this request return terminal slogan), request internalWBEMListener module is the ME2Provider assignment of port numbers.Wherein, and addListener (this, 0, null): the parameter " 0 " in the port request shows that by the internalWBEMListener interface be the ME2Provider assignment of port numbers.Yet, addListener (this, 0, null): 0 among the port can also be replaced by concrete port numbers, if what carry among the addlinstener is concrete port numbers, then refer to ask will this concrete port numbers receive as ME2Provider the port numbers of event.Usually, the form of this request adopts existing request form.Therefore, the embodiment of the invention does not further describe in detail at this.InternalWBEMListener is receiving addListener (this, 0, null): after the port request, be the ME2Provider assignment of port numbers, the internalWBEMListener interface is monitored the port numbers that need to be transmitted to ME2Provider by this port numbers, namely receives the port numbers of the event of CIM server forwarding as ME2Provider.
In addition, addListener (this, 0, null): the object reference information of also carrying receiving terminal in the request of port (: Port represents this request return terminal slogan), inner WBEM monitor interface and with the object reference information of the port numbers of internalWBEMListener interface assignment and ME2Provider as＜key, value mapping stores.
Concrete, internalWBEMListener is receiving addListener (this, 0, null): the handling process after the port request please refer to Fig. 4, because to be that the CIM client increases the flow process of designated ends slogan identical for WBEMListener in flow process shown in Figure 4 and the prior art, the embodiment of the invention at this in detailed description.
Step 303, ME2Provider send to CIMOM and create the inner example request (createInstance (instance of CIM_ListenerDestinationInternal)) of transmitting the destination, the CIM adaptation module of note subsystem are defined as the receiving terminal of event with request.That is, ME2Provider request CIM server sends to ME2Provider with event.The existing CIM client-requested of request reference of described establishment CIM_ListenerDestinationInternal example is with the request of CIM client as the event receiving terminal, and the request of the establishment example that existing CIM client is sent expands, and is that ME2Provider is that internal module in the CIM server is as the receiving terminal of event to show.
Concrete, described request is as follows:
A newly-increased value " 6 " in ValueMap, in Values, increase accordingly " Internal ", show that when the Protocol value is 6 with the internal module of event forwarding to the CIM server, rather than device is processed such as the CIM client beyond sending to the CIM server.
Step 304, ME2Provider send example (createInstance (instance of the CIM_IndicationFilter)) request that creates the indication filter to CIMOM, with the CIM adaptation module of note subsystem the event condition that receives are sent to CIMOM by the CIM_IndicationFilter example.
Concrete, ME2Provider can carry out assignment to the query attribute of CIM_IndicationFilter example, and is as follows: " Select*from CIM_AlertIndication where AlertingManagedElement=' sms center ' ".Wherein, ' sms center ' expression ' object path of sms center (CIMObject Path is referring to DMTF standard text DSP0004CIM_Infrastructure Specification).
Step 305, ME2Provider send event subscription requests to CIMOM, namely create the indication CIM_IndicationSubscription example (request of createInstance (instance of CIM_IndicationSubscription) of subscribing to.This CIM_IndicationSubscriptio example is set up corresponding relation between ListenerDestinationInternal example and IndicationFilter example.Concrete, this step creates to subscribe to existing CIM client-requested indicates the process of example consistent, and the present invention is not described in detail in this.
The receiving terminal of the event that the process of the adaptation module ME3Provider execution in step 301-305 of step 306, integration message system, request CIM server report ME3Provider as ME2Provider.In the present embodiment, the integration message system event that ME2Provider reports that pulls subscription.
(ME1Provider is to CIMOM report and alarm event (deliveryEvent (indication)), and is transmitted to note subsystem Provider by CIMOM through InternalWBEMListener for the adaptation module of step 307-309, sms center.
