Savon 3.0 uses the Logging gem which allows us to use multiple loggers and easily control them from the outside. Please make sure to read the documentation for this library in order to customize logging.

Let me give you an example of how you would change the log level and add a STDOUT appender to the root logger. This basically tells all registered loggers to write everything to STDOUT.

logger = Logging.logger['root']
logger.level = :debug

While the root logger controls all registered loggers, you can also target any single logger by name.
