Instance Method Details

#force_flush(timeout: nil) ⇒ Integer

Export all ended spans to the configured Exporter that have not yet been exported.

This method should only be called in cases where it is absolutely necessary, such as when using some FaaS providers that may suspend the process after an invocation, but before the Processor exports the completed spans.

Parameters:

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

    An optional timeout in seconds.

Returns:

  • (Integer)

    Export::SUCCESS if no error occurred, Export::FAILURE if a non-specific failure occurred, Export::TIMEOUT if a timeout occurred.

  start_time = Time.now
  results = @span_processors.map do |processor|
    remaining_timeout = OpenTelemetry::Common::Utilities.maybe_timeout(timeout, start_time)
    return Export::TIMEOUT if remaining_timeout&.zero?

    processor.force_flush(timeout: remaining_timeout)
  end
  results.uniq.max
end

#on_finish(span) ⇒ Object

Called when a Span is ended, if the Span#recording? returns true.

This method is called synchronously on the execution thread, should not throw or block the execution thread.

Parameters:

  • span (Span)

    the Span that just ended.

def on_finish(span)
  @span_processors.each { |processor| processor.on_finish(span) }
end

#on_start(span, parent_context) ⇒ Object

Called when a Span is started, if the Span#recording? returns true.

This method is called synchronously on the execution thread, should not throw or block the execution thread.

Parameters:

  • span (Span)

    the Span that just started.

  • parent_context (Context)

    the parent Context of the newly started span.

def on_start(span, parent_context)
  @span_processors.each { |processor| processor.on_start(span, parent_context) }
end

#shutdown(timeout: nil) ⇒ Integer

Called when TracerProvider#shutdown is called.

Parameters:

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

    An optional timeout in seconds.

Returns:

  • (Integer)

    Export::SUCCESS if no error occurred, Export::FAILURE if a non-specific failure occurred, Export::TIMEOUT if a timeout occurred.
