◆ EventActivityOptions

enum System.Diagnostics.Tracing.EventActivityOptions

strong

Specifies the tracking of activity start and stop events.

Enumerator
None	Use the default behavior for start and stop tracking.
Disable	Turn off start and stop tracking.
Recursive	Allow recursive activity starts. By default, an activity cannot be recursive. That is, a sequence of Start A, Start A, Stop A, Stop A is not allowed. Unintentional recursive activities can occur if the app executes and for some the stop is not reached before another start is called.
Detachable	Allow overlapping activities. By default, activity starts and stops must be property nested. That is, a sequence of Start A, Start B, Stop A, Stop B is not allowed will result in B stopping at the same time as A.

Definition at line 6 of file EventActivityOptions.cs.

◆ EventChannel

enum System.Diagnostics.Tracing.EventChannel : byte

MicrosoftTelemetry	Attached to all Microsoft telemetry events.
WdiContext	Attached to all Windows Diagnostics Infrastructure (WDI) context events.
WdiDiagnostic	Attached to all Windows Diagnostics Infrastructure (WDI) diagnostic events.
Sqm	Attached to all Service Quality Mechanism (SQM) events.
AuditFailure	Attached to all failed security audit events. Use this keyword only for events in the security log.
AuditSuccess	Attached to all successful security audit events. Use this keyword only for events in the security log.
CorrelationHint	Attached to transfer events where the related activity ID (correlation ID) is a computed value and is not guaranteed to be unique (that is, it is not a real GUID).
EventLogClassic	Attached to events that are raised by using the `RaiseEvent` function.

Definition at line 6 of file EventKeywords.cs.

◆ EventLevel

enum System.Diagnostics.Tracing.EventLevel

strong

Identifies the level of an event.

Enumerator
LogAlways	No level filtering is done on the event.
Critical	This level corresponds to a critical error, which is a serious error that has caused a major failure.
Error	This level adds standard errors that signify a problem.
Warning	This level adds warning events (for example, events that are published because a disk is nearing full capacity).
Informational	This level adds informational events or messages that are not errors. These events can help trace the progress or state of an application.
Verbose	This level adds lengthy events or messages. It causes all events to be logged.

Definition at line 5 of file EventLevel.cs.

◆ EventManifestOptions

enum System.Diagnostics.Tracing.EventManifestOptions

strong

Specifies how the ETW manifest for the event source is generated.

Enumerator
None	No options are specified.
Strict	Causes an exception to be raised if any inconsistencies occur when writing the manifest file.
AllCultures	Generates a resources node under the localization folder for every satellite assembly provided.

DataCollectionStart	A trace collection start event.
DataCollectionStop	A trace collection stop event.
Extension	An extension event.
Reply	An event that is published after an activity in an application replies to an event.
Resume	An event that is published after an activity in an application resumes from a suspended state. The event should follow an event that has the F:System.Diagnostics.Tracing.EventOpcode.Suspend operation code.
Suspend	An event that is published when an activity in an application is suspended.
Send	An event that is published when one activity in an application transfers data or system resources to another activity.
Receive	An event that is published when one activity in an application receives data.

Definition at line 8 of file EventOpcode.cs.

Setting this option is a directive to the ETW listener should use manifest-based format when raising events. This is the default option when defining a type derived from T:System.Diagnostics.Tracing.EventSource using one of the protected T:System.Diagnostics.Tracing.EventSource constructors.
EtwSelfDescribingEventFormat	The ETW listener should use self-describing event format. This is the default option when creating a new instance of the T:System.Diagnostics.Tracing.EventSource using one of the public T:System.Diagnostics.Tracing.EventSource constructors.
