MSCluster_EventResourceStateChange class

A WMI class that represents a resource state change event.

The following syntax is simplified from MOF code, and includes all inherited properties.

Syntax

[Dynamic, Provider("MS_CLUSTER_PROVIDER"), UUID("{F1163D38-0E12-49ed-B0AF-09C683F89243}"), AMENDMENT]
class MSCluster_EventResourceStateChange : MSCluster_EventStateChange
{
  uint8  SECURITY_DESCRIPTOR[];
  uint64 TIME_CREATED;
  uint32 EventTypeMajor;
  uint32 EventTypeMinor;
  string EventObjectName;
  uint32 EventObjectType;
  string EventObjectPath;
  uint32 EventNewState;

  string EventGroup;
};

Members

The MSCluster_EventResourceStateChange class has these types of members:

Properties

The MSCluster_EventResourceStateChange class has these properties.

EventGroup

Data type: string

Access type: Read-only

Current group that contains this resource.

EventNewState

Data type: uint32

Access type: Read-only

Current state of the object that is reporting a state change.

EventObjectType value Enumeration
2 (Node Object)
CLUSTER_NODE_STATE
3 (Group object)
CLUSTER_GROUP_STATE
4 (Resource Object)
CLUSTER_RESOURCE_STATE
6 (Network Object)
CLUSTER_NETWORK_STATE
7 (Network Interface Object)
CLUSTER_NETINTERFACE_STATE

This property is inherited from MSCluster_EventStateChange.

EventNode

Data type: string

Access type: Read-only

Current node that is hosting this group.

EventObjectName

Data type: string

Access type: Read-only

Provides the name of the object to which this event applies.

This property is inherited from MSCluster_Event.

EventObjectPath

Data type: string

Access type: Read-only

Provides the WMI path of the object to which this event applies.

This property is inherited from MSCluster_Event.

EventObjectType

Quorum

Provides the type of object to which this event applies.

This property is inherited from MSCluster_Event.

EventTypeMajor

Data type: uint32

Access type: Read-only

Provides the major event category. A value of 0 indicates an event returned by GetClusterNotify.

This property is inherited from MSCluster_Event.

EventTypeMinor

Data type: uint32

Access type: Read-only

Provides the subtype within the major category. When the EventTypeMajor property is 0, this subtype contains the cluster event value that GetClusterNotify returns.

This property is inherited from MSCluster_Event.

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.

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.

Remarks

The MSCluster_EventResourceStateChange class is derived from the MSCluster_EventStateChange class.
