OSWatcher使用简介

OSWatcher Black Box, 简称OSW，是Oracle提供的一个小但是非常有用的工具，它通过调用OS自己提供的命令来记录OS运行时的一些性能参数，比如CPU/Memory/Swap/Network IO/Disk IO相关的信息。但是部署OSW有很多好处：1. 它比较容易部署，并且容易删除。
2. 资源消耗比较小，不管是从CPU，内存还是磁盘空间来说。
3. 平时不需要维护，并且在发生问题时可以帮我们迅速定位问题是否发生在OS端数据库是运行在OS之上的，如果OS发生了异常，那么数据库肯定也会受到影响；如果我们仅仅从数据库的角度去分析这样的问题时，很难有个好结果.官方博客介绍点击这里。1、下载从MOS上里的文档301137.1上下载OSW，需要有MOS账号或者到Linux公社1号FTP服务器下载------------------------------------------分割线------------------------------------------FTP地址：ftp://ftp1.linuxidc.com用户名：ftp1.linuxidc.com密码：www.linuxidc.com在 2016年LinuxIDC.com12月OSWatcher使用简介下载方法见 http://www.linuxidc.com/Linux/2013-10/91140.htm------------------------------------------分割线------------------------------------------ 2、安装随便找一个目录解压安装，不要在/tmp目录，不必须root用户[oracle@rhel6 ~]$ mkdir oswatcher
[oracle@rhel6 ~]$ mv oswbb734.tar oswatcher/
[oracle@rhel6 ~]$ cd oswatcher/

oswbb/stopOSWbb.shOSWatcher包含两部分：oswbb：这是一个shell脚本，用于收集和存储数据oswbba：这是一个java工具用于分析收集到的数据并提供建议，还可以生成图片或html文档。3、启动OSWatcherstartOSWbb.sh脚本有四个参数：ARG1 = snapshot interval in seconds.
ARG2 = the number of hours of archive data to store.
ARG3 = （optional） the name of a compress utility to compress each file automatically after it is created.
ARG4 = （optional） an alternate （non default） location to store the archive directory.如果不输入任何参数，默认间隔30秒收集一次数据，并且默认保存48小时的数据。默认收集到的数据会存储在解压目录下的archive目录下，这个目录是在第一次启动startOSWbb.sh脚本时创建的。#启动startOSWbb.sh脚本，间隔15秒，保存5天的数据
[oracle@rhel6 oswbb]$ nohup sh startOSWbb.sh 15 120 &
[1] 3131
[oracle@rhel6 oswbb]$ nohup: ignoring input and appending output to `nohup.out"

[1]+ Done nohup sh startOSWbb.sh 15 120
#查看输出日志
[oracle@rhel6 oswbb]$ more nohup.out
Setting the archive log directory to/home/oracle/oswatcher/oswbb/archive

oswbb is looking for the CPU COUNT on your system
CPU COUNT will be used by oswbba to automatically look for cpu problems
