CIM_ClassModification クラス - WMI LibraryCIM_ClassModification クラスの説明
CIM_ClassModification notifies when a class definition in the schema is modified.
プロパティ リスト
Access Type: Read Only The current definition of the class that is created, changed or deleted in the schema. In the case of a CIM_ClassDeletion Indication, the definition for the class just prior to deletion should be placed in this property.
Access Type: Read Only A list of IndicationIdentifiers whose notifications are correlated with (related to) this one.
Access Type: Read Only An identifier for the indication filter that selects this indication and causes it to be sent. This property is to be filled out by the indication sending service. The value shall be correlatable with the Name property of the instance of CIM_IndicationFilter describing the criteria of the indication. The value of the IndicationFilterName should be formatted using the following algorithm: < OrgID > : < LocalID >, where < OrgID > and < LocalID > are separated by a colon (:) and < OrgID > shall include a copyrighted, trademarked, or otherwise unique name that is owned by the business entity that is creating or defining the value or that is a registered ID assigned to the business entity by a recognized global authority. In addition, to ensure uniqueness, < OrgID > shall not contain a colon (:).When using this algorithm, the first colon to appear in the value shall appear between < OrgID > and < LocalID >. < LocalID > is chosen by the business entity and shall be used uniquely.
Access Type: Read Only An identifier for the Indication. This property is similar to a key value in that it can be used for identification, when correlating Indications (see the CorrelatedIndications array). Its value SHOULD be unique as long as correlations are reported, but MAY be reused or left NULL if no future Indications will reference it in their CorrelatedIndications array.To ensure uniqueness, the value of IndicationIdentifier should be constructed using the following "preferred" algorithm:
Access Type: Read Only The time and date of creation of the Indication. The property may be set to NULL if the entity creating the Indication is not capable of determining this information. Note that IndicationTime may be the same for two Indications that are generated in rapid succession.
Access Type: Read Only Holds the value of the user defined severity value when 'PerceivedSeverity' is 1 ("Other").
Access Type: Read Only An enumerated value that describes the severity of the Indication from the notifier's point of view: 1 - Other, by CIM convention, is used to indicate that the Severity's value can be found in the OtherSeverity property. 3 - Degraded/Warning should be used when its appropriate to let the user decide if action is needed. 4 - Minor should be used to indicate action is needed, but the situation is not serious at this time. 5 - Major should be used to indicate action is needed NOW. 6 - Critical should be used to indicate action is needed NOW and the scope is broad (perhaps an imminent outage to a critical resource will result). 7 - Fatal/NonRecoverable should be used to indicate an error occurred, but it's too late to take remedial action. 2 and 0 - Information and Unknown (respectively) follow common usage. Literally, the Indication is purely informational or its severity is simply unknown.
Access Type: Read Only A copy of the 'previous' class definition whose change generated the Indication. PreviousClassDefinition contains an 'older' copy of the class' information, as compared to what is found in the ClassDefinition property (inherited from ClassIndication).
Access Type: Read Only The sequence context portion of a sequence identifier for the indication. The sequence number portion of the sequence identifier is provided by the SequenceNumber property. The combination of both property values represents the sequence identifier for the indication. The sequence identifier for the indication enables a CIM listener to identify duplicate indications when the CIM service attempts the delivery retry of indications, to reorder indications that arrive out-of-order, and to detect lost indications. If a CIM service does not support sequence identifiers for indications, this property shall be NULL. If a CIM service supports sequence identifiers for indications, this property shall be maintained by the CIM service for each registered listener destination, and its value shall uniquely identify the CIM service and the indication service within the CIM service such that restarts of the CIM service and deregistration of listener destinations to the CIM service cause the value to change, without reusing earlier values for a sufficiently long time. When retrying the delivery of an indication, this property shall have the same value as in the original delivery. To guarantee this uniqueness, the property value should be constructed using the following format (defined in ABNF): sequence-context = indication-service-name "#" cim-service-start-id "#" listener-destination-creation-time Where: indication-service-name is the value of the Name property of the CIM_IndicationService instance responsible for delivering the indication. cim-service-start-id is an identifier that uniquely identifies the CIM service start, for example via a timestamp of the start time, or via a counter that increases for each start or restart. listener-destination-creation-time is a timestamp of the creation time of the CIM_ListenerDestination instance representing the listener destination. Since this format is only a recommendation, CIM clients shall treat the value as an opaque identifier for the sequence context and shall not rely on this format.
Access Type: Read Only The sequence number portion of a sequence identifier for the indication. The sequence context portion of the sequence identifier is provided by the SequenceContext property. The combination of both property values represents the sequence identifier for the indication. The sequence identifier for the indication enables a CIM listener to identify duplicate indications when the CIM service attempts the delivery retry of indications, to reorder indications that arrive out-of-order, and to detect lost indications. If a CIM service does not support sequence identifiers for indications, this property shall be NULL. If a CIM service supports sequence identifiers for indications, this property shall be maintained by the CIM service for each registered listener destination, and its value shall uniquely identify the indication within the sequence context provided by SequenceContext. It shall start at 0 whenever the sequence context string changes. Otherwise, it shall be increased by 1 for every new indication to that listener destination, and it shall wrap to 0 when the value range is exceeded. When retrying the delivery of an indication, this property shall have the same value as in the original delivery.
