I am trying to monitor remote directory and files. I need to store or log the changes i.e.(access, write, open and close events) of the files and directories.

I tried using pyinotify for monitoring and recording these events. I achieved it for local system files but my issue is how to monitor the remote files and directories.

Am I able to achieve this with the help of ssh or any other ways are possible to log events occur in remote files and directories?

I have given my code for local system files monitoring.

import pyinotify 
import asyncore 
from .models import AccessEvents 
import threading

class MyEventHandler(pyinotify.ProcessEvent):
    def process_IN_ACCESS(self, event):
        access=AccessEvents(mode_id=1,path=event.pathname)
        access.save()
    def process_IN_ATTRIB(self, event):
        attrib = AccessEvents(mode_id=2, path=event.pathname)
        attrib.save()
    def process_IN_CLOSE_NOWRITE(self, event):
        nwrite = AccessEvents(mode_id=3, path=event.pathname)
        nwrite.save()
    def process_IN_CLOSE_WRITE(self, event):
        write = AccessEvents(mode_id=4, path=event.pathname)
        write.save()
    def process_IN_CREATE(self, event):
        create = AccessEvents(mode_id=5, path=event.pathname)
        create.save()
    def process_IN_DELETE(self, event):
        delete = AccessEvents(mode_id=6, path=event.pathname)
        delete.save()
    def process_IN_MODIFY(self, event):
        modify = AccessEvents(mode_id=7, path=event.pathname)
        modify.save()
    def process_IN_OPEN(self, event):
        open = AccessEvents(mode_id=8, path=event.pathname)
        open.save()

def startmonitor(file_or_dir):
    # watch manager
    wm = pyinotify.WatchManager()
    try:
        test=wm.add_watch(file_or_dir, pyinotify.ALL_EVENTS, rec=True)
        if test[file_or_dir]==-1:
            return 'no_such_file_or_dir'
        else:
            # event handler
            eh = MyEventHandler()
            # notifier
            notifier = pyinotify.AsyncNotifier(wm, eh)
            thread = threading.Thread(target=asyncore.loop(), args=())
            thread.daemon = True  # Daemonize thread
            thread.start()  # Start the execution
            return 'file_monitoring_started'
    except Exception as e:
        print 'error',e

startmonitor('/tmp/test')

If anyone aware of remote system file monitoring, provide me your suggestions. Thanks in Advance!!!

它可以通过简单的客户端-服务器模型（http）来完成。

第一步是您应该在要监视的远程系统上运行文件监视程序代码。以结构化格式保存更改。例如： -

class ChangeEvent:

 def __init__(self, event_name)

 def files_changed(self, list_files)

将这些 ChangeEvents 列表存储为队列（充当缓冲区）。制作一个简单的 GET API，以便客户端可以获取这些更改事件列表。从您发送的队列中删除 ChangeEvents。

现在在客户端应用程序（可能是它的移动或网络，没关系）上，只需定期点击 api（您在上面所做的）以获取更改。

您还可以将这些 ChangeEvents 保存为远程服务器上的 json 或 csv，以进行持久存储。
