func Attributes ¶ Uses

func Attributes(attrs []label.KeyValue) []*commonpb.KeyValue

Attributes transforms a slice of KeyValues into a slice of OTLP attribute key-values.

func CheckpointSet ¶ Uses

func CheckpointSet(ctx context.Context, exportSelector export.ExportKindSelector, cps export.CheckpointSet, numWorkers uint) ([]*metricpb.ResourceMetrics, error)

CheckpointSet transforms all records contained in a checkpoint into batched OTLP ResourceMetrics.

func Record ¶ Uses

func Record(exportSelector export.ExportKindSelector, r export.Record) (*metricpb.Metric, error)

Record transforms a Record into an OTLP Metric. An ErrIncompatibleAgg error is returned if the Record Aggregator is not supported.

func Resource ¶ Uses

func Resource(r *resource.Resource) *resourcepb.Resource

Resource transforms a Resource into an OTLP Resource.

func ResourceAttributes ¶ Uses

func ResourceAttributes(resource *resource.Resource) []*commonpb.KeyValue

ResourceAttributes transforms a Resource into a slice of OTLP attribute key-values.

func SpanData ¶ Uses

func SpanData(sdl []*export.SpanSnapshot) []*tracepb.ResourceSpans

SpanData transforms a slice of SpanSnapshot into a slice of OTLP ResourceSpans.
