If I understand the manual correctly, the python logger is defined as maxon::Loggers::PythonConsole.
Built-In Loggers
All existing loggers are registered at maxon::Loggers. These three loggers can be obtained from these published objects:
maxon::Loggers::Default: The default logger.
maxon::Loggers::PythonConsole: The Python logger.
maxon::Loggers::ProcessConsole: The IDE console logger.
So I guess I just have to change below the Default logger to the Python logger, to get all messages.
However, the namespace does not have a Python logger?
//const maxon::LoggerRef defaultLogger = maxon::Loggers::Default();
const maxon::LoggerRef pythonLogger = maxon::Loggers::PythonConsole();
