OSWatcher Black Box (oswbb)是Oracle开发、提供的一个小巧，但是实用、强大的系统工具，它可以用来抓取操作系统的性能指标，用于辅助监控系统的资源使用。其安装部署、卸载都非常简单；资源消耗也比较小，原理也十分简单，它通过调用OS的的一些命令（例如vmstat、iostat等）来采集、存储CPU/Memory/Swap/Disk IO/Nentwork相关数据。安装和运行oswbba可以帮助在性能诊断时提供丰富多样的各类性能数据、图文报表支持。
OSWatcher 在4.0的版本时被命名为OSWatcher Black Box,简称为oswbb，同时增加了数据分析功能，即OSWatcher Black Box Analyzer (OSWbba)这个绘图和分析工具，其捆绑在 OS Watcher Black Box当中。替代了之前的OSWg。 也就是说在OSWatcher 4.0 之前是：OSWatcher 和 OSWg的关系，OSWatcher 4.0 后变成了： OSWbb 与 OSWbba 的关系。
OSWatcher Black Box（oswbb）支持多个操作系统，也分Linux与Window版本，当然这两个版本有所差别，本篇只讲述Linux版本。另外，OSWatcher Black Box（oswbb）由两个部分组成：
oswbb: 一个Unix的 shell script脚本集合，其用来收集和归档数据，从而帮助定位问题。
oswbba: 一个Java工具来自动分析数据，提供建议，并且生成一个包含图形的 html 文档。
安装与卸载
软件安装
工具卸载
rm -rf oswbb
启动与停止
启动OSWatcher
startOSWbb.sh脚本有四个参数：
ARG1 = snapshot interval in seconds. （间隔时间）
ARG2 = the number of hours of archive data to store. （多长时间）
ARG3 = (optional) the name of a compress utility to compress each file automatically after it is created. （压缩格式）
ARG4 = (optional) an alternate (non default) location to store the archive directory.（存放目录）
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。
启动命令
./startOSWbb.sh 60 10 gzip /u01/soft/oswbb/archive
停止命令
./stopOSWbb.sh
分析OSWatcher收集到的日志
使用oswbba.jar包进行日志的分析，但是jara要在1.4.2及以上版本。
两种方法分析数据
1)生成图形
#cd /u01/oswatcher
#java -jar oswbba.jar -i /u01/oswatcher/archive/ -b May 3 00:00:00 2018 -e May 3 23:59:59 2018
[oracle@rhel6 oswbb]$ export DISPLAY=192.168.56.1:0.0
[oracle@rhel6 oswbb]$ java -jar oswbba.jar -i archive
