Python使用PyInotify持久化日志文件流

Python使用PyInotify持久化日志文件流,python,logging,pyinotify,Python,Logging,Pyinotify,我在通过pyinotify及其线程持久化日志文件写入流时遇到问题。我正在使用pyinotify监视目录中的CLOSE\u WRITE文件事件。在初始化pyinotify之前,我使用内置的logging模块创建一个日志流,如下所示: import os, logging from logging import handlers from logging.config import dictConfig log_dir = './var/log' name = 'com.sadmicrowave

我在通过
pyinotify
及其线程持久化日志文件写入流时遇到问题。我正在使用
pyinotify
监视目录中的
CLOSE\u WRITE
文件事件。在初始化
pyinotify
之前,我使用内置的
logging
模块创建一个日志流,如下所示:

import os, logging
from logging import handlers
from logging.config import dictConfig


log_dir = './var/log'
name = 'com.sadmicrowave.tesseract'
LOG_SETTINGS = { 'version' : 1
                ,'handlers': { 'core': {
                                    # make the logger a rotating file handler so the file automatically gets archived and a new one gets created, preventing files from becoming too large they are unmaintainable. 
                                    'class'     : 'logging.handlers.RotatingFileHandler'
                                    # by setting our logger to the DEBUG level (lowest level) we will include all other levels by default
                                    ,'level'        : 'DEBUG'
                                    # this references the 'core' handler located in the 'formatters' dict element below
                                    ,'formatter'    : 'core'
                                    # the path and file name of the output log file
                                    ,'filename'     : os.path.join(log_dir, "%s.log" % name)
                                    ,'mode'         : 'a'
                                    # the max size we want to log file to reach before it gets archived and a new file gets created
                                    ,'maxBytes'     : 100000
                                    # the max number of files we want to keep in archive
                                    ,'backupCount'  : 5 }
                            }
                             # create the formatters which are referenced in the handlers section above
                            ,'formatters': {'core': {'format': '%(levelname)s %(asctime)s %(module)s|%(funcName)s %(lineno)d: %(message)s' 
                                            }
                            }
                            ,'loggers'   : {'root': {
                                                        'level'     : 'DEBUG' # The most granular level of logging available in the log module
                                                        ,'handlers' : ['core']
                                            }
                            }
                        }

# use the built-in logger dict configuration tool to convert the dict to a logger config
dictConfig(LOG_SETTINGS)

# get the logger created in the config and named root in the 'loggers' section of the config
__log = logging.getLogger('root')
因此,在初始化我的
\u log
变量后,它会立即工作,允许进行日志写入。我想接下来启动
pyinotify
实例,并希望使用以下类定义传递
\uu log

import asyncore, pyinotify

class Notify (object):
    def __init__ (self, log=None, verbose=True):
        wm = pyinotify.WatchManager()
        wm.add_watch( '/path/to/folder/to/monitor/', pyinotify.IN_CLOSE_WRITE, proc_fun=processEvent(log, verbose) )

        notifier = pyinotify.AsyncNotifier(wm, None)
        asyncore.loop()

class processEvent (pyinotify.ProcessEvent):
    def __init__ (self, log=None, verbose=True):
        log.info('logging some cool stuff')

        self.__log              = log
        self.__verbose          = verbose

    def process_IN_CLOSE_WRITE (self, event):
        print event
在上述实现中,我的
process_In_CLOSE_WRITE
方法完全按照预期从
pyinotify.AsyncNotifier
触发;但是,
记录一些很酷的东西的日志行从不写入日志文件

我觉得它与通过pyinotify线程进程持久化文件流有关;然而,我不知道如何解决这个问题


有什么想法吗?

我可能已经找到了一个似乎有效的解决方案。我不确定这是否是最好的方法,所以我将把OP暂时放在一边,看看是否有其他想法被发布

我想我的
pyinotify.AsyncNotifier
设置有误。我将实施更改为:

class Notify (object):
    def __init__ (self, log=None, verbose=True):
        notifiers = []
        descriptors = []
        wm = pyinotify.WatchManager()
        notifiers.append ( pyinotify.AsyncNotifier(wm, processEvent(log, verbose)) )
        descriptors.append( wm.add_watch( '/path/to/folder/to/monitor/', pyinotify.IN_CLOSE_WRITE, proc_fun=processEvent(log, verbose), auto_add=True )

        asyncore.loop()

现在,当我的包装类
processEvents
在侦听器实例化时被触发,并且当事件从
CLOSE\u WRITE
事件触发时,
log
对象被适当地维护和传递,并且可以接收写事件。

不幸的是,一旦我使用
python守护进程
files\u preserve
添加了恶魔化组件,我的日志流再次消失,我的pyinotify事件无法记录到其中
