func Labels Uses

❖
func Labels(output event.Exporter) event.Exporter

Labels builds an exporter that manipulates the context using the event. If the event is type IsLabel or IsStartSpan then it returns a context updated with label values from the event. For all other event types the event labels will be updated with values from the context if they are missing.

func LogWriter Uses

❖
func LogWriter(w io.Writer, onlyErrors bool) event.Exporter

LogWriter returns an Exporter that logs events to the supplied writer. If onlyErrors is true it does not log any event that did not have an associated error. It ignores all telemetry other than log events.

func Spans Uses

❖
func Spans(output event.Exporter) event.Exporter

Spans creates an exporter that maintains hierarchical span structure in the context. It creates new spans on start events, adds events to the current span on log or label, and closes the span on end events. The span structure can then be used by other exporters.

type Printer Uses

❖
type Printer struct {
    // contains filtered or unexported fields
}

func (*Printer) WriteEvent Uses

❖
func (p *Printer) WriteEvent(w io.Writer, ev core.Event, lm label.Map)

type Span Uses

❖
type Span struct {
    Name     string
    ID       SpanContext
    ParentID SpanID
    // contains filtered or unexported fields
}

func GetSpan Uses

❖
func GetSpan(ctx context.Context) *Span

func (*Span) Events Uses

❖
func (s *Span) Events() []core.Event

func (*Span) Finish Uses

❖
func (s *Span) Finish() core.Event

func (*Span) Format Uses

❖
func (s *Span) Format(f fmt.State, r rune)

func (*Span) Start Uses

❖
func (s *Span) Start() core.Event

type SpanContext Uses

❖
type SpanContext struct {
    TraceID TraceID
    SpanID  SpanID
}

func (*SpanContext) Format Uses

❖
func (s *SpanContext) Format(f fmt.State, r rune)

type SpanID Uses

❖

func (SpanID) String Uses

❖
func (s SpanID) String() string

type TraceID Uses

❖
type TraceID [16]byte

func (TraceID) String Uses

❖
func (t TraceID) String() string
