syslog-ng 系列连载-49 ：syslog-ng 命令手册

Name

syslog-ng — syslog-ng system logger application

Synopsis

syslog-ng [options]

Description

The syslog-ng application is a flexible and highly scalable system logging application. 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.
