OSWatcher Black Box, 简称OSW，是oracle提供的一个非常有用的操作系统性能分析工具，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。OSW的工作机制是每隔一段时间调用OS提供的一些工具，比如ps, vmstat, netstat, mpstat, top;然后把这些工具的输出打印到文件里，当系统出现问题时我们可以利用收集的信息帮助我们去分析问题。

OSWatcher支持以下平台：

AIX

Tru64

Solaris

HP-UX

Linux

Windows

1. OSwatch 安装

1.1. OSwatch 下载

下载 OSwatch （ mos 文档 ID 301137.1 ）

网盘路径

通过网盘分享的文件：oswbb840.zip

链接: 百度网盘 请输入提取码

部署在/mysql/osw1/目录下

tar – xvf oswbb840.tar -d /mysql/osw1/

1.2. 部署私网监控（可选，Rac 环境心跳中使用）

在每个节点上，根据 exampleprivate.net 文件， 新增 private.net 文件

注意修改private.net权限为755

chmod 755 private.net

vi private.net

#!/bin/sh
#####################################################################
# This file contains examples of how to monitor private networks. To
# monitor your private networks create an executable file in this same
# directory named private.net. Use the example for your host os below.
# Make sure not to remove the last line in this file. Your file
# private.net MUST contain the rm lock.file line.
#####################################################################
#Solaris Example
#####################################################################
echo "zzz ***"`date`
traceroute -r -F hefei1-priv
traceroute -r -F hefei2-priv
#####################################################################
# DO NOT DELETE THE FOLLOWING LINE!!!!!!!!!!!!!!!!!!!!!
#####################################################################
rm locks/lock.file

1.3. 新增 archive 目录

OSWATCH V7.3.3 以后，如果不指定 archive 目录， osw 默认的 archive 目录为 /app/oracle/tfa/repository/suptools/db01/oswbb/grid/archive, 为了避免影响 /app 目录，建议手工指定 archive 目录。

创建 archive 目录并修改权限

mkdir /osw/oswbb/archive
chmod 775 /osw/oswbb/archive

1.4. 启动 osw

cd /mysql/osw1/oswbb840/oswbb
nohup /mysql/osw1/oswbb840/oswbb/startOSWbb.sh 5 720 gzip /osw/oswbb/archive >/osw/oswbb/startOSW.sh.out 2>&1 &

#其中 5 代表 5 秒收集一次 ,720 代表保留 720 小时 （可根据实际需求调整）。
#gzip /osw/oswbb/archive 代表文件压缩并指定存放位置。

startOSWbb.sh脚本有四个参数：

# $1 = snapshot interval in seconds. #快照收集的频率（秒）

# $2 = the number of hours of archive data to store. #归档数据保留的时间（小时）

# $3 = (optional) the name of the zip or compress utility you want #可选，用于在创建每个文件后自动压缩该文件的压缩实用程序的名称

# OSWbb to use to zip up the archive files upon completion. If

# no zipping is desired set this parameter = NONE. This will

# allow for the $4 parameter below to be recognized as both $3

# and $4 are optional parameters.

# $4 = (optional) the fully qualified name of the archive directory #可选，存储归档目录的备用(非默认)位置。 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。

# where you want oswbb to save your data. This option can be used

# instead of setting the UNIX environment variable OSWBB_ARCHIVE_DEST

# If this parameter is not set oswbb will look for the UNIX

# environment variable OSWBB_ARCHIVE_DEST. If neither are set

# the archive directory will remain in the default location under

# the oswbb directory

例： nohup ./startOSWbb.sh 15 120 gzip &

会每隔15秒搜集一次数据，将结果保留120 小时，并自动压缩生成的文件。

1.4.1. crontab 启动脚本

crontab -e
0,30 * * * * sh /mysql/osw1/oswbb840/oswbb/monosw.sh

vi monosw.sh
----------------------monosw.sh-----------------------------
#!/usr/bin/ksh 
if ps -ef | grep OSWatcher | grep -v grep > /dev/null; then
    echo "$(date): OSWatcher is running." >> /var/log/oswatcher.log
else
    echo "$(date): OSWatcher is not running. Starting..." >> /var/log/oswatcher.log
    sh "$(dirname "$0")/startOSWbb.sh"
fi

1.5. OSW 生成文件查看

1.6. 关闭 osw

/mysql/osw1/oswbb840/oswbb/stopOSWbb.sh

OR

ps -ef |grep OSW |grep -v grep
kill 9 sid

2. OSwatch 数据分析

2.1. 运行前首先检查 java 环境：

[root@db01 oswbb]# java -version
openjdk version "1.8.0_262"
OpenJDK Runtime Environment (build 1.8.0_262-b10)
OpenJDK 64-Bit Server VM (build 25.262-b10, mixed mode)

2.2. 在服务端准备图形界面

2.3. 分析日志

运行 OSWbba 需要用-i 参数指定 archive 目录，这里的目录是 archive 的绝对路径，需要注意的是，这里生成的图形是直接弹出来的，需要用 X Windows.

export LANG=en_US
java -jar /mysql/osw1/oswbb840/oswbb/oswbba.jar -i /mysql/osw1/oswbb840/oswbb/archive


[root@db01 oswbb]# java -jar /mysql/osw1/oswbb840/oswbb/oswbba.jar -i /mysql/osw1/oswbb840/oswbb/archive
