OS Watcher (OSW)系统性能监控软件

OS Watcher简称OSW(oswbb)，用于收集并归档操作系统cpu,memery,disk io,network等相关信息的工具，是oracle提供的脚本工具集，全是shell编写，OSW内部是使用操作系统提供的基本命令来收集数据，给系统带来的额外负载可以安全忽略，收集策略是放在后台定期间隔一段时间自动收集，并可以设定数据保留时间，定期清理。

下载介质

这个工具包可以从Metalink下载。Metalink Note:301137.1， 当前最新为oswbb840版本, 在当前较新的ORACLE 19C RAC安装时，如果选择安装了 TFA 工具集，osw目前已是属于TFA一部分也可以独立安装， 查看当前系统是否启用OSW, 使用 ps -ef|grep osw 查看 oswbb进程是否存在就可以。

OSW is certified to run on the following platforms:
1.AIX
2.Tru64
3.Solaris
4.HP-UX
5.Linux

安装osw

安装很方便，下载后就是一个压缩包，前期版就不到300K，当前也就5M左右，解压就可以使用

[root@oel7db1 ~]# md5sum oswbb840.tar
ccfe01232d1e28e28e5d3999ade773c2 oswbb840.tar
[root@oel7db1 ~]# ls -l oswbb840.tar
-rw-r--r-- 1 root root 5253120 Oct 1 18:21 oswbb840.tar

下面我开始在rhel linux上试验

— 确认所有.sh文件有x执行权限，如果没有 需要授权

[oracle@orazhang osw]$ chmod +x *.sh

对于RAC环境需要配置一下对interconnect使用的private的监控private.net文件， 确认操作系统有traceroute和ifconfig命令， 如果是19c自带TFA方式安装启用的osw不需要配置private.net ，已自动配置完，利用的是osw自带目录中的genprvnet.sh可以生成private.net，当然也可以自己vi 创建这个文件， 如果是RAC 环境，需要上传oswbb 到每个节点，手动执行

[oracle@orazhang osw]$sh  genprvnet.sh

生成当前目录上private.net文件，注意要用x执行权限，如果是vi 手动创建，记的

[oracle@orazhang osw]$ chmod +x private.net

vi 创建private.net的方式是从自带的Exampleprivate.net文件内容中，复制一段适合自己的操作系统平台的内容。如LINUX平台private.net最终内容如下

[oracle@orazhang osw]$ cat private.net
######################################################################
#Linux Example
######################################################################
echo "zzz ***"`date`
traceroute -r -F  192.68.1.xxx
traceroute -r -F  192.68.1.xxx
######################################################################
# DO NOT DELETE THE FOLLOWING LINE!!!!!!!!!!!!!!!!!!!!!
######################################################################
rm locks/lock.file

注意： 上面的traceroute 部分换成自己RAC 环境的实际的private 网络IP, 如可以从cat /etc/hosts中查找private的IP地址。每个实例1条，如4个实例为4条，所有实例的private.net内容一样，可以复制，也可以增加自己指定的探测ip, 如Dataguard。

启动与停止

启动运行./startOSW.sh，后可选3个参数

./startOSW.sh <ARG1> <ARG2> <ARG3>

ARG1:表示收集间隔时间，默认为30秒
ARG1:表示数据保留时间，默认为48小时
ARG3:gzip或不跟，加gzip表示用gzip去压缩收集到的数据
注意：首次运行时会在osw目录下自动 创建archive子目录，用于存放收集到的数据，都是以文件格式存放，间隔30秒采集一次并保留10小时，一般需要120M左右的空间。

调用前先要先确保安装sysstat

[oracle@orazhang osw]$ rpm -qa sysstat
sysstat-7.0.4-2.fc7

建议启动方式

[oracle@orazhang osw]$ sh startOSWbb.sh 3 72 gzip &

以3秒为间隔，保留最后72小时的数据，对于超过保留期限的数据，File Manager 会自动清理（File Manager 每隔一个小时调度一次）,如果进程数较多如，如超过1万里 ps内容可能占空间较大，注意磁盘使用率，可以缩短保留时间如把72改为24.
