尝试一下OSWatch

墨蓝 2022-10-17 15:54 240阅读 0赞

OSWatch是Oracle提供的一个轻量级的操作系统监控工具，之所以说轻量级，一方面是因为无需安装，开箱即用，另一方面，他调用的都是一些系统级的命令，例如top、iostat、netstat，控制好调用频率，消耗就可控。

可以支持主流的操作系统(AIX、LINUX、Solaris、HP-UX、WINDOWS)。

OSWatch的安装文件可以从这篇MOS下载，

OSWatcher (Includes: \[Video\]) (Doc ID 301137.1)。

下载的最新版，解压后，目录结构如下，

![e2bb81255af872b49ac8c341769181df.png][]

运行OSWatch，只需要执行startOSWbb.sh，根据这个脚本的内容注释，他可以接4个参数，

$1，采集快照的间隔，单位是秒。

$2，数据存储的时间，单位是小时。

$3和$4是可选的参数，压缩命令和归档文件夹名称。

其实这些参数，都可不输入，默认按照30秒采集一次存储2天的数据，

![73eb3ca596c05422ef8b279e15453056.png][]

可以看到，以前这个脚本，叫startOSW.sh，从6.0开始，改为startOSWbb.sh，并且支持第四个参数，

![129905a4e809798b6f639d8e58b9352f.png][]

脚本内容很简单，判断下当前是否存在正运行的OSWatch，然后就调用OSWatcher.sh，

![417ff52ab88c443782a9d35bfeb5a7da.png][]

真正的精髓就是OSWatcher.sh，一共1700多行，各种判断调用，考虑了各种环境，风格和细节上，还是很值得学习。

启动这个脚本，他会验证各种要执行的指令，然后就开始30秒一次的采集，

P.S. 可选择后台执行，nohup sh startOSWbb.sh 30 1&

[root@bisal oswbb]# ./startOSWbb.sh 30 1

如果停止脚本，可以杀进程，或者执行stopOSW.sh

[root@bisal oswbb]# ./stopOSW.sh

采集完成，数据会存在archive，

oswatch支持数据分析，看起来更直观，执行这个oswbba.jar，就进入了交互模式，最新版本要求java版本在8以上，

[root@bisal oswbb]# java -jar oswbba.jar -i /opt/software/oswbb/archive/

Please Select an Option:1

应该就是java AWT，

另外一个实用的功能，就是能生成dashboard，相当于汇总数据，输入D，可指定他存储的文件夹名称，

从输出可以看到，生成一系列HTML文件，文件夹中会生成两个文件，

[root@bisal oswbb]# cd analysis/test/
    [root@bisal test]# ls
    analysis.txt  dashboard

一个是文本文件，汇总了相关数据，如下是章节，

图形化展示了采集到的数据，可以点击不同的维度，查看不同的数据，方便且直观，还是比较有用的，
