Python 守护进程 : keep logging

Question

我有一个脚本可以将一些数据记录到磁盘:

logging.basicConfig(filename='davis-debug.log',level=logging.DEBUG)
logging.basicConfig(filename='davis-error.log',level=logging.ERROR)
logging.basicConfig(filename='davis-error.log',level=logging.WARNING)
logging.basicConfig(filename='davis-error.log',level=logging.CRITICAL)

当我像这样使用 python-daemon 时，日志记录停止。

try:
  with daemon.DaemonContext():
  station = VantageProStation()
  station.run()

except KeyboardInterrupt:
  logging.critical('Stopping user aborted with CTRL+C')
pass

我试过 file_preserve，但 logging.basicConfig 没有返回流。
我也不能使用 files_preserve 传递多个流..?
我当然希望我的日志记录继续，我试图将日志定义放在我的类 init 中，但这也没有帮助。

如何在守护进程中配置记录器？这对我有用:

#!/usr/bin/env python

import daemon
import logging
import logging.handlers
from time import sleep
from datetime import datetime

def time_logging_daemon():
    logger = logging.getLogger('time_logging_daemon')
    logger.addHandler(logging.handlers.SysLogHandler(address='/dev/log'))
    logger.setLevel(logging.INFO)
    while True:
        logger.info(datetime.now())
        sleep(1)

with daemon.DaemonContext():
    time_logging_daemon()
