Functions

func Middleware

func Middleware(next http.Handler) http.Handler

Middleware wraps a http.Handler so it's request uri is added to the trace.Span derived from the http.Request's context. This is a workaround for https://github.com/open-telemetry/opentelemetry-go/commit/7b749591320bfcdef2061f4d4f5aa533ab76b47f

func NewExporter

func NewExporter(log accesslog.Logger) tracesdk.SpanExporter

NewExporter creates a new otel SpanExporter which, when added to an otel provider, sends accesslog.Details derived from trace.SpanKindServer spans, to the provided accesslog.Logger.

logger := accesslog.DefaultLogger(nil)
tracer := tracesdk.NewTraceProvider(
	tracesdk.WithBatcher(otelaccesslog.NewExporter(logger)),
)

func SetHandlerName

func SetHandlerName(ctx context.Context, name string)

func WithHandlerName

func WithHandlerName(name string, next http.Handler) http.Handler

WithHandlerName adds name as value to the http.Request's context. It should be used on a per route/handler basis.
