Instance Method Details

#export(span_data, timeout: nil) ⇒ Integer

Called to export sampled SDK::Trace::SpanData structs.

Parameters:

  • span_data (Enumerable<OpenTelemetry::SDK::Trace::SpanData>) —

    the list of recorded SDK::Trace::SpanData structs to be exported.

  • timeout (optional Numeric) (defaults to: nil) —

    An optional timeout in seconds.

Returns:

  • (Integer) —

    the result of the export.

end

#force_flush(timeout: nil) ⇒ Object

Called when SDK::Trace::TracerProvider#force_flush is called, if this exporter is registered to a SDK::Trace::TracerProvider object.

Parameters:
