func NewSpanExporters ¶

func NewSpanExporters(ctx context.Context) ([]trace.SpanExporter, error)

NewSpanExporters returns a list of trace.SpanExporter based on the OTEL_* environment variables which are standardized. Unfortunately, they are not yet supported by opentelemetry-go by default. Once they are, we can likely remove most of this code.
