EventSourceAttribute Class

Definition

Namespace:

System.Diagnostics.Tracing

Assembly:

System.Diagnostics.Tracing.dll

Source:

EventSource.cs

Allows the event tracing for Windows (ETW) name to be defined independently of the name of the event source class.

Remarks

By default, in event tracing for Windows (ETW), the name of an event source matches the name of the event source class, but without the namespace name. This is sufficient for private event sources, but for more visible event sources it is better to have a hierarchical namespace such as: CompanyName.ProviderName. The EventSourceAttribute attribute lets you define the ETW name independently of the name of the class.

The EventSourceAttribute attribute also lets you define a GUID explicitly for the event source. In standard usage, you don't need to specify a GUID when defining an event source or referring to it, because a GUID is implicitly derived from the name of the event source class. Explicitly defining a GUID is discouraged, except when upgrading existing ETW providers to using event sources.

Constructors

EventSourceAttribute()

Initializes a new instance of the EventSourceAttribute class.

Properties

Guid	Gets or sets the event source identifier.
LocalizationResources	Gets or sets the name of the localization resource file.
Name	Gets or sets the name of the event source.
TypeId	When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)
