Functions

func NewTracezHandler

func NewTracezHandler(sp *SpanProcessor) http.Handler

NewTracezHandler returns an http.Handler that can be used to serve HTTP requests for trace zpages.

func SemVersion

func SemVersion() string

SemVersion is the semantic version to be supplied to tracer/meter creation.

Deprecated: Use Version instead.

Types

type SpanProcessor

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

SpanProcessor is an sdktrace.SpanProcessor implementation that exposes zpages functionality for opentelemetry-go.

It tracks all active spans, and stores samples of spans based on latency for non errored spans, and samples for errored spans.

func NewSpanProcessor

func NewSpanProcessor() *SpanProcessor

NewSpanProcessor returns a new SpanProcessor.

func (*SpanProcessor) ForceFlush

func (ssm *SpanProcessor) ForceFlush(context.Context) error

ForceFlush does nothing.

func (*SpanProcessor) OnEnd

func (ssm *SpanProcessor) OnEnd(span sdktrace.ReadOnlySpan)

OnEnd processes all spans and reports them with zpages.

func (*SpanProcessor) OnStart

func (ssm *SpanProcessor) OnStart(_ context.Context, span sdktrace.ReadWriteSpan)

OnStart adds span as active and reports it with zpages.

func (*SpanProcessor) Shutdown

func (ssm *SpanProcessor) Shutdown(context.Context) error

Shutdown does nothing.
