Package nrcensus provides an exporter for sending OpenCensus stats and traces to New Relic.

    To use, simply instantiate a new Exporter using `nrcensus.NewExporter` with your service name and Insights API key and register it with the OpenCensus view and/or trace API.

    exporter, err := nrcensus.NewExporter("My-OpenCensus-App", "__YOUR_NEW_RELIC_INSIGHTS_API_KEY__")
    if err != nil {
    // create stats, traces, etc

      Exporter implements trace.Exporter ( and view.Exporter ( It enables sending of trace and view data from OpenCensus applications to New Relic.

      func NewExporter

      func NewExporter(serviceName, apiKey string, options ...func(*telemetry.Config)) (*Exporter, error)

        NewExporter creates a new Exporter. serviceName is the name of this service or application. apiKey is required and refers to a New Relic Insights Insert API key.

        func (*Exporter) ExportSpan

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

          ExportSpan implements trace.Exporter and records spans with the Harvester for later sending to New Relic.

          func (*Exporter) ExportView

          func (e *Exporter) ExportView(vd *view.Data)

            ExportView implements view.Exporter and records metrics with the Harvester for later sending to New Relic.
