系统日志（Syslog） NETGEAR WS-C3560V2-24TS-E_网络交换机常见问题_技术支持

答案：

这一部分描述系统日志（Syslog）的特性。

概述

系统日志（Syslog）

允许您存储系统信息和(或)错误
可以存储在交换机本地文件或者运行了syslog程序的远程服务器
是从多个系统收集信息日志的方法

稳定的日志文件

目前三个-每个的最后三个会话

每个日志包含两部分

系统启动后的头32个启动日志信息
当启动日志满了以后，最后收到的32个操作日志

文件以ASCII格式保存

slog0.txt – slog2.txt
oog0.txt – olog2.txt

0为启动，1为最后启动，2为上次启动;第三个将在下次启动覆盖。

可以保存在本地以及时显示最新的信息

日志文件说明

<130>JAN01 00:00:060.0.0.0-1 UNKN [0x800023]:bootos.c(386)4 %% Event (0xaaaaaaaa)


A B C	D	E	F	G	H	I

A. 优先级
B. 时间戳
C. 堆叠号
D. 类型名称
E. 类型标识
F. 文件名
G. 行号
