I want to redirect twistd.py's logging to python's logging. When starting a .tac file normally I can easily do this:
from twisted.python.log import PythonLoggingObserver, ILogObserver
from twisted.application import service
application = service.Application("FooApp")
application.setComponent(ILogObserver, PythonLoggingObserver().emit)
However, I don't seem to have an Application when writing an IPlugin. Instead I just have a class that implements IServiceMaker and IPlugin, where makeService returns a service.Service. How can I set this log observer?
Note that I don't just want to add a python logging observer, I want to redirect twistd's logging so that it only goes through python's built-in logging system.
Look at twistd's --logger parameter:
# mylogger.py
from twisted.python import log
def logger():
return log.PythonLoggingObserver().emit
and then invoke twistd: twistd --logger=mylogger.logger.
