oracle系统监控工具oswatch简介！
oswatch（简称osw）是oracle的一个操作系统监控工具，oswatch是一个轻量级的操作系统监控工具，通过调用系统的命令完成信息的收集，并形成历史数据，命令如下：ps ，top ，mpstat ，iostat，netstat ，traceroute vmstat 。支持的操作系统有AIX ，Tru64 ，Solaris ，HP-UX ，Linux 。 可以在metlink直接下载：OS Watcher User Guide [ID 301137.1] （Metalink Note:301137.1） 下载的就是tar包，然后直接解压就可以使用的。osw是一个java应用，可以在服务器上运行。
注意：osw工具需要以root用户来操作哦！
1、安装部署（解压既可）
[root@linux app]# pwd /u01/app [root@linux app]# ll osw302.tar -rw-r--r-- 1 oracle oinstall 1366016 12-13 02:02 osw302.tar [root@linux app]# tar xvf osw302.tar osw/ osw/Exampleprivate.net osw/OSWatcher.sh osw/OSWatcherFM.sh osw/OSWgREADME.txt osw/iosub.sh osw/mpsub.sh osw/oswg.jar osw/oswib.sh osw/oswlnxio.sh osw/oswlnxtop.sh osw/oswnet.sh osw/oswrds.sh osw/oswsub.sh osw/pssub.sh osw/startOSW.sh osw/stopOSW.sh osw/tarupfiles.sh osw/topaix.sh osw/topsub.sh osw/vmsub.sh osw/tmp/ osw/src/ osw/src/coe_logo.gif osw/src/missing_graphic.gif osw/src/oswg_input.txt osw/src/OSW_profile.htm osw/src/Thumbs.db osw/src/tombody.gif osw/src/watch.gif osw/README.txt [root@linux app]# ll osw/ 总计 1336 -rwxr-xr-x 1 1003 dba 1730 2009-08-20 Exampleprivate.net -rwxr-xr-x 1 1003 dba 549 2009-08-20 iosub.sh -rwxr-xr-x 1 1003 dba 549 2009-08-20 mpsub.sh -rwxr-xr-x 1 1003 dba 4451 2009-08-20 OSWatcherFM.sh -rwxr-xr-x 1 1003 dba 22511 2011-05-04 OSWatcher.sh -rw-r--r-- 1 1003 dba 1226302 2011-02-11 oswg.jar -rw-r--r-- 1 1003 dba 14781 2011-05-04 OSWgREADME.txt -rwxr-xr-x 1 1003 dba 415 2009-08-20 oswib.sh -rwxr-xr-x 1 1003 dba 659 2009-08-20 oswlnxio.sh -rwxr-xr-x 1 1003 dba 829 2009-08-20 oswlnxtop.sh -rwxr-xr-x 1 1003 dba 357 2009-08-20 oswnet.sh -rwxr-xr-x 1 1003 dba 826 2009-08-20 oswrds.sh -rwxr-xr-x 1 1003 dba 529 2009-08-20 oswsub.sh -rwxr-xr-x 1 1003 dba 549 2009-08-20 pssub.sh -rw-r--r-- 1 1003 dba 8513 2011-05-04 README.txt drwxr-xr-x 2 1003 dba 4096 2009-08-31 src -rwxr-xr-x 1 1003 dba 1638 2011-02-11 startOSW.sh -rwxr-xr-x 1 1003 dba 560 2009-08-20 stopOSW.sh -rwxr-xr-x 1 1003 dba 127 2009-08-20 tarupfiles.sh drwxr-xr-x 2 1003 dba 4096 2009-08-20 tmp -rwxr-xr-x 1 1003 dba 431 2009-08-20 topaix.sh -rwxr-xr-x 1 1003 dba 550 2009-08-20 topsub.sh -rwxr-xr-x 1 1003 dba 549 2009-08-20 vmsub.sh
从上面看，权限有点怪，不过不管它，继续！
2、启动监控器
启动监控就是调用startOSW.sh脚本。
# ./startOSW.sh arg1 arg2
arg1：数据收集的间隔，以秒为单位。
arg2: 数据收集多长时间，以小时为单位。
例如：
[root@linux osw]# cd /u01/app/osw/ [root@linux osw]# pwd /u01/app/osw [root@linux osw]# ./startOSW.sh 30 1 [root@linux osw]# Testing for discovery of OS Utilities... VMSTAT found on your system. IOSTAT found on your system. MPSTAT found on your system. NETSTAT found on your system. TOP found on your system. Discovery completed. Starting OSWatcher v3.0.2 on 2011年 12月 13日 星期二 02:27:42 CST With SnapshotInterval = 30 With ArchiveInterval = 1 OSWatcher - Written by Carl Davis, Center of Expertise, Oracle Corporation Starting Data Collection... osw heartbeat:2011年 12月 13日 星期二 02:27:42 CST osw heartbeat:2011年 12月 13日 星期二 02:28:13 CST osw heartbeat:2011年 12月 13日 星期二 02:28:44 CST ... ...以上这里就是没30秒采样一次，连续采用一个小时。
初次使用会在OSW_HOME目录下面生成一个archive目录，此目录就是存放采样信息的：
[root@linux osw]# cd /u01/app/osw/ [root@linux osw]# pwd /u01/app/osw [root@linux osw]# ll archive/ 总计 36 drwxr-xr-x 2 root root 4096 12-13 02:16 oswiostat drwxr-xr-x 2 root root 4096 12-13 02:16 oswmeminfo drwxr-xr-x 2 root root 4096 12-13 02:16 oswmpstat drwxr-xr-x 2 root root 4096 12-13 02:16 oswnetstat drwxr-xr-x 2 root root 4096 12-13 02:16 oswprvtnet drwxr-xr-x 2 root root 4096 12-13 02:16 oswps drwxr-xr-x 2 root root 4096 12-13 02:16 oswslabinfo drwxr-xr-x 2 root root 4096 12-13 02:16 oswtop drwxr-xr-x 2 root root 4096 12-13 02:16 oswvmstat [root@linux osw]# cd archive/ [root@linux archive]# ll 总计 36 drwxr-xr-x 2 root root 4096 12-13 02:16 oswiostat drwxr-xr-x 2 root root 4096 12-13 02:16 oswmeminfo drwxr-xr-x 2 root root 4096 12-13 02:16 oswmpstat drwxr-xr-x 2 root root 4096 12-13 02:16 oswnetstat drwxr-xr-x 2 root root 4096 12-13 02:16 oswprvtnet drwxr-xr-x 2 root root 4096 12-13 02:16 oswps drwxr-xr-x 2 root root 4096 12-13 02:16 oswslabinfo drwxr-xr-x 2 root root 4096 12-13 02:16 oswtop drwxr-xr-x 2 root root 4096 12-13 02:16 oswvmstat
3、停止监控器
停止osw就是在其它终端运行stopOSW.sh脚本
例如：
[root@linux osw]# cd /u01/app/osw/ [root@linux osw]# pwd /u01/app/osw [root@linux osw]# ./stopOSW.sh
4、生成图形
[root@linux ~]# cd /u01/app/osw/ [root@linux osw]# pwd /u01/app/osw [root@linux osw]# java -jar oswg.jar -i ./archive/ Starting OSWg V3.0.1 OSWatcher Graph Written by Oracle Center of Expertise Copyright (c) 2008 by Oracle Corporation Parsing Data. Please Wait... Parsing file linux_iostat_11.12.13.0500.dat ... Timestamp Error. Expected format: May 3 16:11:12 2006. Timestamp Error. Found format: 12月 13日 星期二 CST Timestamp Error.

Program aborting...在生成图形界面的时候报错了，注意Timestamp Error. 产生这个错误的原因就是我的操作系统是中文环境的，osw要英文日期格式才可以。
[root@linux osw]# echo $LANG zh_CN.GB18030 [root@linux osw]# date 2011年 12月 13日 星期二 05:03:13 CST下面删除archive目录，改为英文环境就可以了：
[root@linux osw]# LANG=C [root@linux osw]# date Tue Dec 13 05:03:47 CST 2011 [root@linux osw]# rm -rf archive/ [root@linux osw]# ./startOSW.sh 10 1 [root@linux osw]# Testing for discovery of OS Utilities...

[root@linux osw]# ./stopOSW.sh生成图形界面：
