Best bet is to look into the —logger parameter which you can use to pass a custom logger to twistd.

Hi Daniel,

Thank you for your response. Logger option sets the name of the logger factory which should create something which implements ILogObserver. But still - it's part of the legacy api (twisted.python.log). I'm wondering what's the right way to use new logging system here...

You can most definitely use the new logging system with the —logger parameter. Here is an untested example:

from twisted import logger

def myLogger():

    outFile = open('/path/to/log.txt', 'w')
    observer = logger.textFileLogObserver(outFile)
    loglevel = logger.LogLevel.levelWithName('info')
    predicate = logger.LogLevelFilterPredicate()
    predicate.setLogLevelForNamespace("", loglevel)
    filter = logger.FilteringLogObserver(observer, [predicate])

    return filter

twistd [whatever] --logger=mypackage.mymodule.myLogger
