Functions

func ExtractSpanAndTraceID

func ExtractSpanAndTraceID(r *http.Request) (traceID, spanID string)

ExtractSpanAndTraceID extracts span and trace IDs from an http request header.

func InstrumentedTransport

func InstrumentedTransport(baseTransport http.RoundTripper, spanNameCtxValue interface{}, tp sdktrace.TracerProvider) http.RoundTripper

InstrumentedTransport returns the transport to use in client requests. It takes in a transport to wrap, e.g. http.DefaultTransport, and the request context value to pull the span name out from. 99% sure this is wrapping a wrapped thing and totally redundant. Fix later.

func OtlpGrpcExporter

func OtlpGrpcExporter(ctx context.Context, opts ...Option) (sdktrace.SpanExporter, error)

OtlpGrpcExporter uses the otlptracegrpc modules and the otlptrace module to produce a new exporter at our default addr

Types

type Option

type Option interface {
	// contains filtered or unexported methods
}

func WithAddress

func WithAddress(addr string) Option

WithAddress takes an address in the form of Host:Port
