Types

type GRPCIncomingConfig added in v0.11.0

type GRPCIncomingConfig struct {
	GRPCParserHook GRPCTraceParserHook
}

GRPCIncomingConfig stores configuration options relevant to gRPC requests that are handled by a wrapped gRPC interceptor provided in the hnygrpc package.

type GRPCOutgoingConfig added in v1.1.0

type GRPCOutgoingConfig struct {
	GRPCPropagationHook GRPCTracePropagationHook
}

GRPCOutgoingConfig stores configuration options relevant to gRPC requests being sent by an instrumented application.

type GRPCTraceParserHook added in v0.11.0

type GRPCTraceParserHook func(context.Context) *propagation.PropagationContext

GRPCTraceParserHook is a function that will be invoked on all incoming gRPC requests when it is passed as a parameter to an interceptor wrapper function such as the one provided in the hnygrpc package. It can be used to create a PropagationContext object using trace context propagation headers in the provided context. It is functionally identical to its HTTP counterpart, HTTPTraceParserHook.

type GRPCTracePropagationHook added in v1.1.0

type GRPCTracePropagationHook func(*propagation.PropagationContext) metadata.MD

GRPCTracePropagationHook is a function that will be invoked on all outgoing gRPC requests when it is passed as a parameter to a client interceptor wrapper function such as the one provided in the hnygrpc package. It can be used to create a gRPC metadata object that will be injected into the outgoing request. It is functionally identical to its HTTP counterpart, HTTPTracePropagationHook.

type HTTPIncomingConfig

type HTTPIncomingConfig struct {
	HTTPParserHook HTTPTraceParserHook
}

HTTPIncomingConfig stores configuration options relevant to HTTP requests that are handled by a wrapper.

type HTTPOutgoingConfig

type HTTPOutgoingConfig struct {
	HTTPPropagationHook HTTPTracePropagationHook
}

HTTPOutgoingConfig stores configuration options relevant to HTTP requests being sent by an instrumented application.

type HTTPTraceParserHook

type HTTPTraceParserHook func(*http.Request) *propagation.PropagationContext

HTTPTraceParserHook is a function that will be invoked on all incoming HTTP requests when it is passed as a parameter to an http.Handler wrapper function such as the one provided in the hnynethttp package. It can be used to create a PropagationContext object using trace context propagation headers in the provided http.Request. It is expected that this hook will use one of the unmarshal functions exported in the propagation package for a number of supported formats (e.g. Honeycomb, AWS, W3C Trace Context, etc).

type HTTPTracePropagationHook

type HTTPTracePropagationHook func(*http.Request, *propagation.PropagationContext) map[string]string

HTTPTracePropagationHook is a function that will be invoked on all outgoing HTTP requests when it is passed as a parameter to a RoundTripper wrapper function such as the one provided in the hnynethttp package. It can be used to create a map of header names to header values that will be injected in the outgoing request. The information in the provided http.Request can be used to make decisions about what headers to include in the outgoing request, for example based on the hostname of the target of the request. The information in the provided PropagationContext should be used to create the serialized header values. It is expected that this hook will use one of the marshal functions exported in the propagation package for a number of supported formats (e.g. Honeycomb, AWS, W3C Trace Context, etc).
