AsyncCausalityTracer AsyncCausalityTracer AsyncCausalityTracer AsyncCausalityTracer Class

Indicates that a previously created asynchronous operation has completed all of its asynchronous work.

public : static void TraceOperationCompletion(CausalityTraceLevel traceLevel, CausalitySource source, PlatForm::Guid platformId, unsigned __int64 operationId, AsyncStatus status)public static void TraceOperationCompletion(CausalityTraceLevel traceLevel, CausalitySource source, Guid platformId, UInt64 operationId, AsyncStatus status)Public Static Function TraceOperationCompletion(traceLevel As CausalityTraceLevel, source As CausalitySource, platformId As Guid, operationId As UInt64, status As AsyncStatus) As void// You can use this method in JavaScript.

Remarks

This function is used to indicate that a previously created asynchronous operation has completed all of its asynchronous work. The only work that the operation may schedule after logging completion is its completion continuation. The operationId and platformId parameters must match an asynchronous operation that was previously logged by a call to the TraceOperationCreation method.

Logs the creation of an asynchronous operation.

public : static void TraceOperationCreation(CausalityTraceLevel traceLevel, CausalitySource source, PlatForm::Guid platformId, unsigned __int64 operationId, PlatForm::String operationName, unsigned __int64 relatedContext)public static void TraceOperationCreation(CausalityTraceLevel traceLevel, CausalitySource source, Guid platformId, UInt64 operationId, String operationName, UInt64 relatedContext)Public Static Function TraceOperationCreation(traceLevel As CausalityTraceLevel, source As CausalitySource, platformId As Guid, operationId As UInt64, operationName As String, relatedContext As UInt64) As void// You can use this method in JavaScript.

Remarks

Use the TraceOperationCreation method to log the creation of an asynchronous operation. An asynchronous operation represents a group of zero or more related synchronous work items that may be scheduled in an asynchronous way. Each asynchronous operation has a 128-bit GUID that identifies the operation type, like BCL task and WinJS Promise, and a UInt64 operation identifier that must be unique within the platform for the lifetime of the asynchronous operation. Good choices for operationId include a native pointer to an underlying object, or an integer that's incremented for each new operation. The operationName should be a human readable description of the asynchronous work. The relatedContext associates any additional information related to this operation.

Logs the relation between the currently running synchronous work item and a specific asynchronous operation that it's related to.

public : static void TraceOperationRelation(CausalityTraceLevel traceLevel, CausalitySource source, PlatForm::Guid platformId, unsigned __int64 operationId, CausalityRelation relation)public static void TraceOperationRelation(CausalityTraceLevel traceLevel, CausalitySource source, Guid platformId, UInt64 operationId, CausalityRelation relation)Public Static Function TraceOperationRelation(traceLevel As CausalityTraceLevel, source As CausalitySource, platformId As Guid, operationId As UInt64, relation As CausalityRelation) As void// You can use this method in JavaScript.

Remarks

Causality relations track ways that synchronous work items may interact with asynchronous operations.

Raised when a client starts listening to the causality trace.

public : static event EventHandler TracingStatusChanged<TracingStatusChangedEventArgs>public static event EventHandler TracingStatusChanged<TracingStatusChangedEventArgs>Public Static Event TracingStatusChanged<TracingStatusChangedEventArgs>// You can use this event in JavaScript.

Remarks

The logging level and flags are passed to enable fine-grained decisions about which instrumentation points should be enabled.

The TracingStatusChanged event is raised when logging is disabled.
