Do you mean "emit structured log text to stdout"?  In that case, that is covered in the document you link to; these two sections:

http://twistedmatrix.com/documents/current/core/howto/logger.html#avoid-mutable-event-keys
http://twistedmatrix.com/documents/current/core/howto/logger.html#starting-the-global-log-publisher

create a jsonFileLogObserver and start logging to it:

import sys
from twisted.logger import jsonFileLogObserver, globalLogBeginner, Logger
globalLogBeginner.beginLoggingTo([jsonFileLogObserver(sys.stdout)])
log = Logger()
log.info("Information.")

If you want unstructured log output for human reading (not a good choice for an automated system, but perhaps useful for debugging), you can instead go with textFileLogObserver, in almost exactly the same way:

import sys
from twisted.logger import textFileLogObserver, globalLogBeginner, Logger
globalLogBeginner.beginLoggingTo([textFileLogObserver(sys.stdout)])
log = Logger()
log.info("Information.")

Is this what you were looking for?
