Syntax

public sealed class TraceDecisionPredicate

Properties

Default

A default TraceDecisionPredicate that only disables tracing health checks.

Declaration

public static TraceDecisionPredicate Default { get; }

Property Value

Type	Description
TraceDecisionPredicate

DoNothing

A TraceDecisionPredicate that does not have any effect on trace decisions and does not disable tracing health checks.

Declaration

public static TraceDecisionPredicate DoNothing { get; }

Property Value

Type	Description
TraceDecisionPredicate

Methods

Create(Func<HttpRequest, Nullable<Boolean>>, Boolean)

Creates a TraceDecisionPredicate.

Declaration

public static TraceDecisionPredicate Create(Func<HttpRequest, bool?> traceDecisionPredicate, bool ignoreHealthChecks = true)

Parameters

Type	Name	Description
System.Func<System.Web.HttpRequest, System.Nullable<System.Boolean>>	traceDecisionPredicate	Used to determine if a request should be traced. Takes an System.Web.HttpRequest. It should return true if the request should be traced, false if the request should not be traced and null if the decision should be left to other sampling mechanisms. Must not be null.
System.Boolean	ignoreHealthChecks	Optional. True if Google App Engine health check requests should not be traced. Defaults to true.

Returns

Type	Description
TraceDecisionPredicate

Remarks

Ignoring of health checks (ignoreHealthChecks) takes precedence over the predicate (traceDecisionPredicate). If ignoreHealthChecks is true and the request is a health check traceDecisionPredicate will not be called.

ShouldTrace(HttpRequest)

Used to determine if a request should be traced. This will not override a trace header decision.

Declaration

public bool? ShouldTrace(HttpRequest request)

Parameters

Type	Name	Description
System.Web.HttpRequest	request	The HTTP request to check.

Returns

Type	Description
System.Nullable<System.Boolean>	True if the request should be traced, false if the request should not be traced and null if the decision should be left to other sampling mechanisms.
