Types

type Exporter

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

Exporter is an implementation of trace.Exporter that uploads spans to a Zipkin server.

func NewExporter

func NewExporter(reporter reporter.Reporter, localEndpoint *model.Endpoint) *Exporter

NewExporter returns an implementation of trace.Exporter that uploads spans to a Zipkin server.

reporter is a Zipkin Reporter which will be used to send the spans. These can be created with the openzipkin library, using one of the packages under github.com/openzipkin/zipkin-go/reporter.

localEndpoint sets the local endpoint of exported spans. It can be constructed with github.com/openzipkin/zipkin-go.NewEndpoint, e.g.:

localEndpoint, err := NewEndpoint("my server", listener.Addr().String())

localEndpoint can be nil.

func (*Exporter) ExportSpan

func (e *Exporter) ExportSpan(s *trace.SpanData)

ExportSpan exports a span to a Zipkin server.
