how to redirect the logging output of xmlrpc server to some file

Question

I'm using the SimpleXMLRPCServer module to create a rpc server. Whenever i send any request to server it shows me the connection request. How can i redirect this output to some file so that i can see the request made to the server later.

this is my script for server

from SimpleXMLRPCServer import SimpleXMLRPCServer
from SimpleXMLRPCServer import SimpleXMLRPCRequestHandler
import logging
import os
import string
from subprocess import Popen,PIPE 
import xmlrpclib
# Set up logging
logging.basicConfig(level=logging.DEBUG, filename = 'RPCServer.log')
class FileOperation():
'''Class to perform file operation on the Remote machine'''
    def __init__(self):
       self.fh = None
       self.os = os            #adding built-in OS module functionality
       self.string = string    #adding built-in String module functionality

# Restrict to a particular path.

class RequestHandler(SimpleXMLRPCRequestHandler):
    rpc_paths = ('/RPC2',)
# Create server
server = SimpleXMLRPCServer(("localhost", 8000), requestHandler = RequestHandler,allow_none = True, logRequests = True)
server.register_introspection_functions()
server.register_instance(FileOperation(),allow_dotted_names = True )


# Run the server's main loop
try:
    print 'Use Control-C to exit'
    server.serve_forever()
except KeyboardInterrupt:
    print 'Exiting'

Whenever I send any request I'll get o/p like this -

Use Control-C to exit
127.0.0.1 - - [11/Dec/2013 11:34:29] "POST /RPC2 HTTP/1.1" 200 -
127.0.0.1 - - [11/Dec/2013 11:34:30] "POST /RPC2 HTTP/1.1" 200 -
127.0.0.1 - - [11/Dec/2013 11:34:31] "POST /RPC2 HTTP/1.1" 200 -
127.0.0.1 - - [11/Dec/2013 11:34:32] "POST /RPC2 HTTP/1.1" 200 -
127.0.0.1 - - [11/Dec/2013 11:34:33] "POST /RPC2 HTTP/1.1" 200 -
127.0.0.1 - - [11/Dec/2013 11:34:34] "POST /RPC2 HTTP/1.1" 200 -
127.0.0.1 - - [11/Dec/2013 11:34:35] "POST /RPC2 HTTP/1.1" 200 -

How can i redirect this o/p to some file. I set the file name in logging config but the o/p doesn't go there

The messages are written to sys.stderr. You can either

1. Redirect stderr, or
2. In your subclass of SimpleXMLRPCRequestHandler override the method log_message and use logging there if you wish.

The original method is BaseHTTPRequestHandler.log_message in module BaseHTTPServer and looks like this:

def log_message(self, format, *args):
    """Log an arbitrary message.

    This is used by all other logging functions.  Override
    it if you have specific logging wishes.

    The first argument, FORMAT, is a format string for the
    message to be logged.  If the format string contains
    any % escapes requiring parameters, they should be
    specified as subsequent arguments (it's just like
    printf!).

    The client host and current date/time are prefixed to
    every message.

    """

    sys.stderr.write("%s - - [%s] %s\n" %
                     (self.address_string(),
                      self.log_date_time_string(),
                      format%args))
