简介

参考文档 (Doc ID 301137.1)
包括两个工具：

1. oswbb 数据收集工具，是一组shell程序，程序中调用: top, vmstat, iostat, mpstat, netstat,
   and traceroute等os的监控工具；
2. oswbba 数据分析工具，可以产生图形界面
   windows平台没有这个工具，windows平台用Cluster Health Monitor ，可以参考文档 736752.1 。

启动和停止oswbb

启动脚本startOSWbb.sh 有四个参数
ARG1 = snapshot interval in seconds.
ARG2 = the number of hours of archive data to store.
ARG3 = (optional) the name of a compress utility to compress each file automatically after it is created.
ARG4 = (optional) an alternate (non default) location to store the archive directory.
默认参数是 30 和 48 表示每30秒收集一次信息，存放48小时。
sudo nohup ./startOSWbb.sh 30 240 & 表示每30秒收集一次数据，数据保存10天，后台运行。

sudo nohup ./startOSWbb.sh &

Info...You did not enter a value for snapshotInterval.
Info...Using default value = 30
Info...You did not enter a value for archiveInterval.
Info...Using default value = 48
Setting the archive log directory to/home/oracle/oracle.ahf/tfa/ext/oswbb/archive

Discovery of CPU CORE COUNT
CPU CORE COUNT will be used by oswbba to automatically look for cpu problems

CPU CORE COUNT = 24
VCPUS/THREADS = 48

Discovery completed.

oswbb heartbeat:Wed Mar 18 15:59:11 CST 2020
[oracle@base-test-01 oswbb]$ 

停止用stopOSWbb.sh
收集的数据存放在archive目录下，格式如下：
<node_name>_<OS_utility>_YY.MM.DD.HH24.dat

启动oswbba

oswbba 用于分析 OSWatcher (oswbb) 收集的数据。可以产生图形界面。
运行：

java -jar oswbba.jar -i /home/oracle/oracle.ahf/tfa/ext/oswbb/archive

出现过下面的错误：

把archive和analyze目录删除后重新运行即可。

分析

生成dashboard

Please Select an Option:d
Enter a unique analysis/dashboard directory name or enter <CR> to accept default name:
