>>> import cherrypy
>>> envs= cherrypy._cpconfig.environments #dictionary
>>> envs['embedded']
{'checker.on': True, 'engine.SIGTERM': None, 'request.show_mismatched_params': True, 'request.show_tracebacks': True, 'engine.autoreload_on': False, 'tools.log_headers.on': True, 'log.screen': True, 'engine.SIGHUP': None}
>>> envs['production']
{'request.show_tracebacks': False, 'log.screen': False, 'request.show_mismatched_params': False, 'checker.on': False, 'engine.autoreload_on': False, 'tools.log_headers.on': False}
