Functions ¶

func Start ¶

func Start(ctx context.Context, name string) (context.Context, trace.Span)

Types ¶

type Observer ¶

type Observer struct {
	// contains filtered or unexported fields
}

An Observer handles tracing, logging and metrics exporting.

func NewObserver ¶

func NewObserver(ctx context.Context, projectID, serverName string) (_ *Observer, err error)

NewObserver creates an Observer. The context is used to flush traces in AfterRequest, so it should be longer-lived than any request context. (We don't want to use the request context because we still want traces even if it is canceled or times out.)

func (*Observer) Observe ¶

func (o *Observer) Observe(h http.Handler) http.Handler

Observe adds metrics and tracing to an http.Handler.
