1. 概述
--------------
使用oracle的osw工具，可以对系统的cpu和内存，磁盘等进行图形化的展示，对于把握和了解整体的资源使用情况，具有直观的效果。
osw工具由一系列shell脚本构成，
oswatcher.sh是主调程序，派生出许多单个的shell进程，使用unix的操作系统诊断工具，来收集特定类型的数据
osw调用特定的操作系统工具，每个工具作为一个特定的后台进程，进行数据收集。
一般而言支持下述工具：
ps
top
mpstat
iostat
netstat
traceroute
vmstat
输出结果可以进行图形化的展示，当然，也可以使用shell脚本对收集的archive信息进行处理。
--------------
2. 支持平台
--------------
osw可以运行于下述平台之上:
aix
tru64
solaris
hp-ux
linux
这个工具要去metlinke上下载 不过可以到linuxidc.com的ftp资源上下载
下载在linux公社的1号ftp服务器里，，下载地址：
ftp地址：ftp://www.linuxidc.com
用户名：
密码：
在 2012年linuxidc.com\9月\oracle os watcher 安装与错误处理
下载方法见
这个工具可以在oracle用户下安装,不必要在root下
oracle] tar -xvf osw301.tar
>cd osw
4. 启动与停止
--------------
./startosw.sh 60 10
./stoposw.sh
nohup ./startosw.sh 60 10 &
60：数据收集的间隔，以秒为单位
10: 数据收集多长时间，以小时为单位
5. 图形化输出展示
