Functions

func ContextWithSpanSampling

func ContextWithSpanSampling(ctx context.Context, shouldSample bool) context.Context

func NewDelayedSpanProcessor

func NewDelayedSpanProcessor(
	exporter sdktrace.SpanExporter,
	options ...DelayedSpanProcessorOption,
) sdktrace.SpanProcessor

Types

type DelayedSpanProcessorOption

type DelayedSpanProcessorOption func(*delayedSpanProcessorOptions)

func WithBatchTimeout

func WithBatchTimeout(d time.Duration) DelayedSpanProcessorOption

func WithExportTimeout

func WithExportTimeout(d time.Duration) DelayedSpanProcessorOption

func WithMaxExportBatchSize

func WithMaxExportBatchSize(n int) DelayedSpanProcessorOption

func WithMaxLatency

func WithMaxLatency(d time.Duration) DelayedSpanProcessorOption

func WithMaxQueueSize

func WithMaxQueueSize(n int) DelayedSpanProcessorOption

func WithMaxTotalSpans

func WithMaxTotalSpans(n int) DelayedSpanProcessorOption

func WithOnError

func WithOnError(b bool) DelayedSpanProcessorOption

func WithTraceIDFraction

func WithTraceIDFraction(fraction float64) DelayedSpanProcessorOption

func WithTraceIDFractionScoped

func WithTraceIDFractionScoped(fractions map[string]float64) DelayedSpanProcessorOption

type LookupCardinalityDetector

type LookupCardinalityDetector func(string) cardinalitydetector.Detector

type Sampler

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

func NewSampler

func NewSampler(fallback sdktrace.Sampler) *Sampler

func (*Sampler) Description

func (s *Sampler) Description() string

Description returns information describing the Sampler.

func (*Sampler) ShouldSample

func (s *Sampler) ShouldSample(params sdktrace.SamplingParameters) sdktrace.SamplingResult

ShouldSample checks the context for shouldSampleKey and returns a sampling decision based on that. Otherwise, it delegates to the fallback sampler.

type TracerProvider

type TracerProvider struct {
	*sdktrace.TracerProvider
	// contains filtered or unexported fields
}

func NewTracerProvider

func NewTracerProvider(
	ctx context.Context,
	cardinalityDetectorOptions cardinalitydetector.Options,
	opts ...sdktrace.TracerProviderOption,
) *TracerProvider

func (*TracerProvider) Shutdown

func (p *TracerProvider) Shutdown(ctx context.Context) error

Shutdown implements trace.TracerProvider.

func (*TracerProvider) Tracer

func (p *TracerProvider) Tracer(name string, options ...trace.TracerOption) trace.Tracer

Tracer implements trace.TracerProvider.
