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

Members

The MSFT_UCTraceEventBase class has these types of members:

• Properties

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.
