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.
