syslog-ng 系列连载-9 ：syslog-ng 的体系

2.1. The philosophy of syslog-ng

Typically, syslog-ng is used to manage log messages and implement centralized logging, where the aim is to collect the log messages of several devices on a single, central log server. The different devices — called syslog-ng clients — all run syslog-ng, and collect the log messages from the various applications, files, and other sources. The clients send all important log messages to the remote syslog-ng server, where the server sorts and stores them.

# 注释 ：一般来说，syslog-ng 是用于管理日志和实现集中日志记录的。

# 它分成两部分 ：client 和 server ，这两者上面都需要运行 syslog-ng

#     -）1、client 端的责任是从不同的应用程序、文件、或者其他的数据源收集日志，并发送到日志服务器

#     -）2、server 端的责任是接收日志并推它们进行排序和存储
