本文介绍了Oracle官方工具Oswatch的安装与使用，包括解压、安装JDK、启动监控、查看和分析系统状态，以及OSWbba的图形化分析。重点展示了如何配置和运行Oswatcher来收集CPU、内存、磁盘I/O和进程信息。
Oswatch是oracle官方提供，用于收集操作系统性能的小工具，oswatch的安装与使用也比较简单，直接解压就可以使用。oswatch是通过调用系统的命令完成信息的收集，如：ps ，top ，mpstat ，iostat，netstat ，traceroute vmstat 。支持的操作系统包括AIX，Solaris ，Linux等 。
1、解压oswbb软件到指定的目录
######这里我使用的是v8.4的版本，直接放到root目录下
[root@oracle19c ~]# tar xvf oswbb840.tar
oswbb/
oswbb/uncpr.bat
oswbb/sarsub.sh
oswbb/psmemsub.sh
oswbb/stopOSWbb.sh
oswbb/analysis/
oswbb/piddsub.sh
oswbb/arpsub.sh
oswbb/docs/
oswbb/docs/OSWatcher/
oswbb/docs/OSWatcher/oswbb_README.txt
2、安装jdk8.0以上版本，oswbba需要调用
#####解压jdk8.0版本到指定目录
[root@oracle19c archive]# tar xzvf jdk1.8.0_11.tar.gz
#####设置java home环境变量
vi .bash_profile
JAVA_HOME=/root/jdk1.8.0_11
PATH=$JAVA_HOME/bin:$HOME/bin
3、启动Oswatcher收集系统资源状态
######设置lang环境变量
[root@oracle19c oswbb]# export LANG=zh_US
[root@oracle19c oswbb]# date
Fri Aug 27 15:44:39 CST 2021
[root@oracle19c oswbb]#
#####示例：启动oswbb.sh 以5秒钟一次并删除1个小时前的归档数据，收集的数据存放在archive目录，默认1个小时进行归档
[root@oracle19c oswbb]# ./startOSWbb.sh 5 1 gzip /root/oswbb/archive/
[root@oracle19c oswbb]# Info...Zip option IS specified.
Info...OSW will use /root/oswbb/archive/ to compress files.
Setting the archive log directory to/root/oswbb/archive
Testing for discovery of OS Utilities...
VMSTAT found on your system.
IOSTAT found on your system.
MPSTAT found on your system.
IP found on your system.
TOP found on your system.
PIDSTAT found on your system.
NFSIOSTAT found on your system.
TRACEROUTE found on your system.
Discovery of CPU CORE COUNT
CPU CORE COUNT will be used by oswbba to automatically look for cpu problems
CPU CORE COUNT = 4
VCPUS/THREADS = 4
Discovery completed.

4、到archive目录，看到到已经收集到的系统状态
#####进入到archive，查看已经收集到的数据
[root@oracle19c oswbb]# cd archive/
[root@oracle19c archive]# ls
oswarp oswcpuinfo oswifconfig oswiostat oswmeminfo oswmpstat oswnetstat oswnfsiostat oswpidstat oswpidstatd oswprvtnet oswps oswslabinfo oswtop oswvmstat oswxentop
[root@oracle19c archive]#
#######查看已经收集到的磁盘io信息
[root@oracle19c archive]# cd oswiostat/
[root@oracle19c oswiostat]#
[root@oracle19c oswiostat]#
[root@oracle19c oswiostat]# cat oracle19c_iostat_21.08.27.1500.dat |more
