Logging ======= pyfusion uses the standard python loggers. The default is to log info and above (not debug) into a file, and warning and above to the console. The configuation is changed by the logging.cfg file, whose contents are described in https://docs.python.org/2/library/logging.config.html#logging-config-fileformat partial example: # this connect both those described below [logger_root] level=DEBUG handlers=consoleHandler, fileHandler [handler_fileHandler] class=FileHandler level=DEBUG formatter=simpleFormatter args=('pyfusion.log', 'w') [handler_consoleHandler] class=StreamHandler level=WARNING formatter=simpleFormatter args=(sys.stdout,)
