Python中syslog功能代码

参考网址：http://csl.name/py-syslog-win32/

在我们日常工作中，我们需要从Windows系统上发送syslog消息到syslog服务器。下面的代码能够工作的很好。

你能下载syslog.py代码：http://csl.name/py-syslog-win32/syslog.py

"""

Python syslog client.

This code is placed in the public domain bythe author.

Written by Christian Stigen Larsen.

This is especially neat for Windows users,who (I think) don't

get any syslog module in the default pythoninstallation.

See RFC3164 for more info --http://tools.ietf.org/html/rfc3164

Note that if you intend to send messages toremote servers, their

syslogd must be started with -r to allow toreceive UDP from

the network.

import socket

# I'm a python novice, so I don't know ofbetter ways to define enums

FACILITY = {

       'kern':0, 'user': 1, 'mail': 2, 'daemon': 3,

       'auth':4, 'syslog': 5, 'lpr': 6, 'news': 7,

       'uucp':8, 'cron': 9, 'authpriv': 10, 'ftp': 11,

       'local0':16, 'local1': 17, 'local2': 18, 'local3': 19,

       'local4':20, 'local5': 21, 'local6': 22, 'local7': 23,

}

LEVEL = {

       'emerg':0, 'alert':1, 'crit': 2, 'err': 3,

       'warning':4, 'notice': 5, 'info': 6, 'debug': 7

}

def syslog(message, level=LEVEL['notice'],facility=FACILITY['daemon'],

       host='localhost',port=514):

       """

       Sendsyslog UDP packet to given host and port.

       """

       sock= socket.socket(socket.AF_INET, socket.SOCK_DGRAM)

       data= '<%d>%s' % (level + facility*8, message)

       sock.sendto(data,(host, port))

       sock.close()

示例用法：

from syslog import syslog

syslog('There were zwei peanuts walking downder strasse...', host='brit.ain')

为了让它工作，你必须确保syslog服务接收远程消息。你能通过使用-r选项启动syslogd。

我也喜欢Pyton docstring有多么的好，例如：

$ python
