Types

type JaegerTracer

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

JaegerTracer wraps an opentracing tracer with a jaeger reporter.

func (JaegerTracer) Close

func (jt JaegerTracer) Close() error

Close closes the tracer.

func (JaegerTracer) Extract

func (jt JaegerTracer) Extract(format interface{}, carrier interface{}) (opentracing.SpanContext, error)

Extract wraps Extract.

func (JaegerTracer) Inject

func (jt JaegerTracer) Inject(sm opentracing.SpanContext, format interface{}, carrier interface{}) error

StartSpan wraps Inject.

func (JaegerTracer) StartSpan

func (jt JaegerTracer) StartSpan(operationName string, opts ...opentracing.StartSpanOption) opentracing.Span

StartSpan wraps StartSpan.

type Tracer

type Tracer interface {
	StartSpan(operationName string, opts ...opentracing.StartSpanOption) opentracing.Span
	Inject(sm opentracing.SpanContext, format interface{}, carrier interface{}) error
	Extract(format interface{}, carrier interface{}) (opentracing.SpanContext, error)
	Close() error
}

Tracer defines the open tracing interface.

func NewJaegerTracer

func NewJaegerTracer(serviceName, reporterHostName, reporterPort string) (Tracer, error)

NewJaegerTracer returns a traces with defaults.
