Activity.TraceIdGenerator Property

Definition

Namespace:

System.Diagnostics

Assembly:

System.Diagnostics.DiagnosticSource.dll

Package:

System.Diagnostics.DiagnosticSource v9.0.0-preview.3.24172.9

Source:

Activity.cs

When starting an Activity which does not have a parent context, the Trace Id will automatically be generated using random numbers. TraceIdGenerator can be used to override the runtime's default Trace Id generation algorithm.

public:
 static property Func<System::Diagnostics::ActivityTraceId> ^ TraceIdGenerator { Func<System::Diagnostics::ActivityTraceId> ^ get(); void set(Func<System::Diagnostics::ActivityTraceId> ^ value); };

public static Func<System.Diagnostics.ActivityTraceId>? TraceIdGenerator { get; set; }

static member TraceIdGenerator : Func<System.Diagnostics.ActivityTraceId> with get, set

Public Shared Property TraceIdGenerator As Func(Of ActivityTraceId)

Property Value

Func<ActivityTraceId>

Remarks

• TraceIdGenerator needs to be set only if the default Trace Id generation is not enough for the app scenario. - When setting TraceIdGenerator, ensure it is performant enough to avoid any slowness in the Activity starting operation. - If TraceIdGenerator is set multiple times, the last set will be the one used for the Trace Id generation. - Setting TraceIdGenerator to null will re-enable the default Trace Id generation algorithm.
