It's trivial to write a log observer that does so. Below is a snippet
from my app that writes errors  (logged with log.err) to the win32
event log. The servicemanager module is part of pywin32.


import servicemanager

def ErrorLogger(msg):
    """ A log observer which will write error messages
    to the windows event log

    Usage: log.addObserver(ErrorLogger)
    """
    if not "isError" in msg:
        return
    if not msg["isError"]:
        return
    #the value is sometimes (often? always?) a tuple
    messages = list(msg["message"])
    if "failure" in msg:
        thisFailure = msg["failure"]
        messages.append(thisFailure.getTraceback(detail="verbose"))
    message = '\n'.join(str(l) for l in messages)
    servicemanager.LogErrorMsg(message)
