MSFT_UCTraceEventBase class

The MSFT_UCTraceEventBase class is the base class that is used to fire tracing events for observing the outcome of an execution by an updating consumer. Clients can subscribe to these tracing events to facilitate debugging of scenarios. All tracing events must inherit from MSFT_UCTraceEventBase.

Note  For more information about support and installation of this component on a specific operating system, see Operating System Availability of WMI Components.

Syntax

class MSFT_UCTraceEventBase : __ExtrinsicEvent
{
  uint32                CommandIndex;
  MSFT_UpdatingConsumer REF Consumer;
  string                ErrorStr;
  object                Event;
  string                ExecutionId;
  uint8                 SECURITY_DESCRIPTOR[];
  uint32                StatusCode;
  uint64                TIME_CREATED;
};

Members

The MSFT_UCTraceEventBase class has these types of members:

Properties

The MSFT_UCTraceEventBase class has these properties.

CommandIndex
Data type: uint32
Access type: Read-only

Index of the statement that is currently being executed.

Consumer
Data type: MSFT_UpdatingConsumer
Access type: Read-only

Reference to an instance of the updating consumer that is being executed.

ErrorStr
Data type: string
Access type: Read-only

Information about an error (StatusCode greater than 1). For example, if an updating consumer contains an UPDATE statement that is not valid, the ErrorStr property contains information about the part of the query that is not valid.

Event
Data type: object
Access type: Read-only

Event that is indicated to the updating consumer.

ExecutionId
Data type: string
Access type: Read-only

Unique identifier that represents the execution of the updating consumer. Each execution of an updating consumer for an event has a unique identifier. The identifier permits correlation of the command trace events because all commands executed to update a consumer have the same ExecutionId value.

SECURITY_DESCRIPTOR
Data type: uint8 array
Access type: Read-only

Descriptor that the event provider uses to determine the users that can receive an event. This property is inherited from __ExtrinsicEvent.

StatusCode
Data type: uint32
Access type: Read-only

Status code that represents the outcome of a command or consumer trace event.

TIME_CREATED
Data type: uint64
Access type: Read-only

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