OSWatcher Black Box (oswbb)是Oracle開(kāi)發(fā)、提供的一個(gè)小巧，但是實(shí)用、強(qiáng)大的系統(tǒng)工具，它可以用來(lái)抓取操作系統(tǒng)的性能指標(biāo)，用于輔助監(jiān)控系統(tǒng)的資源使用。其安裝部署、卸載都非常簡(jiǎn)單；資源消耗也比較小，原理也十分簡(jiǎn)單，它通過(guò)調(diào)用OS的的一些命令（例如vmstat、iostat等）來(lái)采集、存儲(chǔ)CPU/Memory/Swap/Disk IO/Nentwork相關(guān)數(shù)據(jù)。安裝和運(yùn)行oswbba可以幫助在性能診斷時(shí)提供豐富多樣的各類(lèi)性能數(shù)據(jù)、圖文報(bào)表支持。
OSWatcher 在4.0的版本時(shí)被命名為OSWatcher Black Box,簡(jiǎn)稱(chēng)為oswbb，同時(shí)增加了數(shù)據(jù)分析功能，即OSWatcher Black Box Analyzer (OSWbba)這個(gè)繪圖和分析工具，其捆綁在 OS Watcher Black Box當(dāng)中。替代了之前的OSWg。 也就是說(shuō)在OSWatcher 4.0 之前是：OSWatcher 和 OSWg的關(guān)系，OSWatcher 4.0 后變成了： OSWbb 與 OSWbba 的關(guān)系。
? ? ? OSWatcher Black Box（oswbb）支持多個(gè)操作系統(tǒng)，也分Linux與Window版本，當(dāng)然這兩個(gè)版本有所差別，本篇只講述Linux版本。另外，OSWatcher Black Box（oswbb）由兩個(gè)部分組成：
oswbb: 一個(gè)Unix的 shell script腳本集合，其用來(lái)收集和歸檔數(shù)據(jù)，從而幫助定位問(wèn)題。
oswbba: 一個(gè)Java工具來(lái)自動(dòng)分析數(shù)據(jù)，提供建議，并且生成一個(gè)包含圖形的 html 文檔。
安裝與卸載
軟件安裝
工具卸載
rm -rf oswbb
啟動(dòng)與停止
啟動(dòng)OSWatcher
startOSWbb.sh腳本有四個(gè)參數(shù)：
ARG1 = snapshot interval in seconds.?（間隔時(shí)間）
ARG2 = the number of hours of archive data to store.?（多長(zhǎng)時(shí)間）
ARG3 = (optional) the name of a compress utility to compress each file automatically after it is created.?（壓縮格式）
ARG4 = (optional) an alternate (non default) location to store the archive directory.（存放目錄）
如果不輸入任何參數(shù)，默認(rèn)間隔30秒收集一次數(shù)據(jù)，并且默認(rèn)保存48小時(shí)的數(shù)據(jù)。
默認(rèn)收集到的數(shù)據(jù)會(huì)存儲(chǔ)在解壓目錄下的archive目錄下，這個(gè)目錄是在第一次啟動(dòng)startOSWbb.sh腳本時(shí)創(chuàng)建的。
啟動(dòng)命令
./startOSWbb.sh 60 10 gzip /u01/soft/oswbb/archive
停止命令
./stopOSWbb.sh
分析OSWatcher收集到的日志
使用oswbba.jar包進(jìn)行日志的分析，但是jara要在1.4.2及以上版本。
兩種方法分析數(shù)據(jù)
1)生成圖形
