A description of the value for the HostingSystemFormat property when it is set to "1" (other). For other values of HostingSystemFormat, OtherHostingSystemFormat must be set to NULL.

OtherPerceivedSeverity

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("Msvm_FailoverIndication.PerceivedSeverity")

A description of the value for the PerceivedSeverity property when it is set to "1" (other). For other values of PerceivedSeverity, OtherPerceivedSeverity must be set to NULL.

OtherPreviousHostingSystemFormat

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("Msvm_FailoverIndication.PreviousHostingSystemFormat")

A description of the value for the PreviousHostingSystemFormat property when it is set to "1" (other). For other values of PreviousHostingSystemFormat, OtherPreviousHostingSystemFormat must be set to NULL.

OtherSeverity

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_AlertIndication.PerceivedSeverity")

The severity of the indication from the notifier's point of view when PerceivedSeverity is set to "1" (Other).

This property is inherited from CIM_Indication.

PerceivedSeverity

Data type: uint16

Access type: Read-only

Qualifiers: Required, Override ("PerceivedSeverity")

The severity of the failover indication from the notifier's point of view.

The possible values are:

Unknown (0)

Other (1)

Information (2)

Degraded/Warning (3)

Minor (4)

Critical (6)

Fatal/NonRecoverable (7)

PreviousHostingSystem

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("Msvm_FailoverIndication.HostingSystemFormat")

The identifying information of the instance that hosts the element referenced by HostedElement. This property contains the path of the instance, encoded as a string if the instance is modeled in the CIM Schema. If the instance is not a CIM instance, this property contains the name of the entity. The path or name is formatted according the PreviousHostingSystemFormat property.

PreviousHostingSystemFormat

Data type: uint16

Access type: Read-only

Qualifiers: ModelCorrespondence ("Msvm_FailoverIndication.PreviousHostingSystem", "Msvm_FailoverIndication.OtherPreviousHostingSystemFormat")

The format of the PreviousHostingSystem property.

The possible values are:

Unknown (0)

The format is unknown.

Other (1)

SECURITY_DESCRIPTOR

Data type: uint8 array

Access type: Read-only

Descriptor used by the event provider to determine which users can receive the event. This property is inherited from __Event. For more information about constants used to set this security descriptor, see WMI Security Constants.

SequenceContext

Data type: string

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_Indication.SequenceNumber")

The sequence context of the sequence identifier for the indication. If a service does not support sequence identifiers for indications, this property should be set to NULL. If the indication is redelivered, this property remains the same.

Note

The sequence identifier for the indication enables a listener to identify duplicate indications when the service attempts to redeliver indications, reorder indications that arrive out of order, and detect lost indications.

To ensure that SequenceContext is unique, it should use the following format:

  • indication-service-name#cim-service-start-id #listener-destination-creation-time
  • indication-service-name is the value of the Name property of the CIM_IndicationService instance that delivers the indication.
  • cim-service-start-id is an identifier that uniquely identifies the start operation of a service. For example, this could be a timestamp of the start time, or a counter that increases for each start or restart of the service.
  • listener-destination-creation-time is a timestamp of the creation time of the CIM_ListenerDestination instance representing the listener destination.nSince 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.

This property is inherited from CIM_Indication.

SequenceNumber

Data type: sint64

Access type: Read-only

Qualifiers: ModelCorrespondence ("CIM_Indication.SequenceContext")

The sequence number of the sequence identifier for the indication.

Note

The sequence identifier for the indication enables a listener to identify duplicate indications when the service attempts to redeliver indications, reorder indications that arrive out of order, and detect lost indications.

The sequence number has the following characteristics:

  • The sequence number is reset to "0" whenever the SequenceContext value changes.
  • Whenever the listener destination receives a new indication, the sequence number is increased by "1".
  • The sequence number wraps to "0" when the value range is exceeded.
  • If the indication is redelivered, the SequenceNumber remains the same.

This property is inherited from CIM_Indication.

TIME_CREATED

Data type: uint64

Access type: Read-only

Unique value that indicates the time at which the event was generated. This is a 64-bit value that represents the number of 100-nanosecond intervals after January 1, 1601. The information is in the Coordinated Universal Times (UTC) format. This property is inherited from __Event.

For more information about using uint64 values in scripts, see Scripting in WMI.
