Functions

func Attributes

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

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

func CheckpointSet

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

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

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

func Resource

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

Resource transforms a Resource into an OTLP Resource.

func ResourceAttributes

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

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

func SpanData

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

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