syslog中的多行日志记录

Question

所以我已经配置我的Python应用程序使用Python的SysLogHandler登录到syslog,一切正常.除了多线处理.并不是说我需要如此糟糕地发出多行日志记录(我做了一点),但我需要能够阅读Python的异常.我正在使用Ubuntu和rsyslog 4.2.0.这就是我得到的:

Mar 28 20:11:59 telemachos root: ERROR 'EXCEPTION'#012Traceback (most recent call last):#012  File "./test.py", line 22, in <module>#012    foo()#012  File "./test.py", line 13, in foo#012    bar()#012  File "./test.py", line 16, in bar#012    bla()#012  File "./test.py", line 19, in bla#012    raise Exception("EXCEPTION!")#012Exception: EXCEPTION!

测试代码,以备不时之需:

import logging
from logging.handlers import SysLogHandler

logger = logging.getLogger()
logger.setLevel(logging.INFO)
syslog = SysLogHandler(address='/dev/log', facility='local0')
formatter = logging.Formatter('%(name)s: %(levelname)s %(message)r')
syslog.setFormatter(formatter)
logger.addHandler(syslog)

def foo():
    bar()

def bar():
    bla()

def bla():
    raise Exception("EXCEPTION!")

try:
    foo()
except:
    logger.exception("EXCEPTION")

Answer 1

或者,如果要将syslog保持在一行上以进行解析,则只需在查看日志时替换字符即可.

tail -f /var/log/syslog | sed 's/#012/\n\t/g'

Answer 2

好的,终于搞清楚了......

默认情况下,rsyslog会转义所有奇怪的字符(ASCII <32),这包括换行符(以及制表符和其他).只需将其添加到您的rsyslog配置中即可将其关闭:
