Functions

func ObserveWithTrace

func ObserveWithTrace(ctx context.Context, o prometheus.Observer, v float64)

ObserveWithTrace observes the value, providing the traceID as an exemplar if exemplars are supported and a traceID is present

func StartSpan

func StartSpan(
	ctx context.Context,
	name string,
	opts ...trace.SpanStartOption,
) (context.Context, trace.Span)

StartSpan starts a trace with the given context

Types

type RequestTracePropagator

type RequestTracePropagator struct {
	RequestHeader *pb.RequestHeader
