Python的监控功能示例

pyinotify 就是通过 调用系统的inotify来实现通知的

Inotify 既可以监视文件，也可以监视目录

Inotify 使用系统调用而非 SIGIO 来通知文件系统事件。

Inotify 可以监视的文件系统事件包括：

案例：Python监控目录变化

#!/usr/bin/env python
#coding=utf-8
 
import os
from pyinotify import WatchManager, Notifier, ProcessEvent, IN_DELETE, IN_CREATE,IN_MODIFY
wm = WatchManager() 
mask = IN_DELETE | IN_CREATE |IN_MODIFY  # watched events
 
class PFilePath(ProcessEvent):
  def process_IN_CREATE(self, event):
    print  "Create file: %s " %  os.path.join(event.path, event.name)
 
  def process_IN_DELETE(self, event):
    print  "Delete file: %s " %  os.path.join(event.path, event.name)
 
  def process_IN_MODIFY(self, event):
      print  "Modify file: %s " %  os.path.join(event.path, event.name)
 
if __name__ == "__main__":
 
  notifier = Notifier(wm, PFilePath())
  wdd = wm.add_watch('.', mask, rec=True)
 
  while True:
    try :
      notifier.process_events()
      if notifier.check_events():
        notifier.read_events()
    except KeyboardInterrupt:
      notifier.stop()
      break
