func (*LogExporter) ExportMetrics ¶

func (e *LogExporter) ExportMetrics(ctx context.Context, metrics []*metricdata.Metric) error

ExportMetrics exports to log.

func (*LogExporter) ExportSpan ¶

type Options ¶

type Options struct {
	// ReportingInterval is a time interval between two successive metrics
	// export.
	ReportingInterval time.Duration

	// MetricsLogFile is path where exported metrics are logged.
	// If it is nil then the metrics are logged on console
	MetricsLogFile string

	// TracesLogFile is path where exported span data are logged.
	// If it is nil then the span data are logged on console
	TracesLogFile string
}

Options provides options for LogExporter

PrintExporter is a stats and trace exporter that logs the exported data to the console.

The intent is help new users familiarize themselves with the capabilities of opencensus.

This should NOT be used for production workloads.

func (*PrintExporter) ExportSpan ¶

func (e *PrintExporter) ExportSpan(vd *trace.SpanData)

ExportSpan logs the trace span.

func (*PrintExporter) ExportView ¶

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