Python 客户端/服务器实时传输日志文件更新？
我们在 Solaris 10 服务器上有生成文本日志文件的应用程序。我们需要将这些日志文件实时传输到中央服务器以监控新事件。
理想情况下，我们有一个 NFS 挂载，我们所有的系统都会将日志写入那里，监控服务器可以从那里提取它们。不幸的是，由于技术和非技术原因，这不是一个选择。
目前，我们使用后台 tail -f 通过 SSH 隧道传输数据。
然而，我们正在考虑是否值得将一些更强大的东西组合在一起。
我正在考虑使用 Twistedb（或类似的东西 - 建议？）编写一个简单的 Python 客户端/服务器来流式传输日志数据。这是很容易就能实现的事情吗？我可以从现有的库/工具中寻找想法吗？有什么我应该注意的问题吗？
另外，这是 Solaris 10，所以我不熟悉文件系统监视器的状态。我知道 Gamin 可以通过 OpenCSW 获得。但是，还有其他选择吗？
We have applications on Solaris 10 servers that generate text logfiles. We need to stream these logfiles in realtime to a central server for monitoring of new events.
Ideally we'd have a NFS-mount, and all our system would write their logs to there, and the monitoring server could just pull them up from there. Unfortunately, for technical and non-technical reasons that's not an option here.
At the moment, we're using a backgrounded tail -f to pipe the data over an SSH tunnel.
However, we were looking at whether it's worth putting together something a bit more robust.
I was thinking of writing a simple Python client/server with Twistedb (or something similar - recommendations?) to stream the log data. Is this something that's easily achievable? Any existing libraries/tools I could look to for ideas? Any issues I should be aware of?
Also, this is Solaris 10, so I'm not familiar with the state of filesystem monitors. I do know Gamin is available via OpenCSW. however, are there any other choices out there?

查看 Python 的日志记录模块。 http://docs.python.org/library/logging.html
它包含以下功能记录到文件、流、系统日志、网络服务器等。该食谱包含示例或通过网络进行日志记录。 http://docs.python.org/howto/logging-cookbook.html #logging-cookbook
该模块也相当容易扩展。
Check out Python's logging module. http://docs.python.org/library/logging.html
It contains the capability to log to files, streams, syslog, networked servers, and more. The cookbook contains examples or logging over the network. http://docs.python.org/howto/logging-cookbook.html#logging-cookbook
The module is fairly easy to extend also.
请考虑使用 zeromq，而不是原始套接字。它不是消息代理服务器，而是一个让您编写消息传递系统的库。它可以通过 TCP、IPC（是的，进程间！）、多播和其他协议轻松实现跨平台和与语言无关的通信。只需将 python 组件替换为 C 组件，它就可以像以前一样工作。
它是满足您“..借口学习..”需求的完美软件；-)
但最精彩的部分是在您的 Solaris 设置中构建它。 Python 绑定位于 http://pypi.python.org/pypi/pyzmq/2.1.9
Do consider zeromq, instead of raw sockets. Its no message broker server, its a library to let you write your message passing system. It enables easy cross-platform and language-agnostic communication over TCP, IPC (yes,inter-process!), multicast and other protocols. Simply swap a python component with a C component and it just works as before.
Its the perfect software to satisfy your "..excuse to learn.." ;-)
But the show-stopper would be building it in your Solaris setup. Python bindings are at http://pypi.python.org/pypi/pyzmq/2.1.9
