1.概述

使用oracle的osw工具，可以對系統的CPU和記憶體，磁碟等進行圖形化的展示，對於把握和了解整體的資源使用情況，具有直觀的效果。

OSW工具由一系列shell指令碼構成，

OSWatcher.sh是主調程式，派生出許多單個的shell程式，使用unix的作業系統診斷工具，來收集特定型別的資料

OSW呼叫特定的作業系統工具，每個工具作為一個特定的後臺程式，進行資料收集。

一般而言支援下述工具：

ps

top

ifconfig

mpstat

iostat

netstat

traceroute

vmstat

meminfo(Linux Only)

slabinfo(Linux Only)

輸出結果可以進行圖形化的展示，當然，也可以使用shell指令碼對收集的archive資訊進行處理。

2.支援平臺

OSW可以執行於下述平臺之上:

AIX

Solaris

HP-UX

Linux

3.上傳

使用sftp上傳oswbb734.tar至/opt/tools路徑下（工具可選，路徑可選）

4.解壓檔案

tar xvf oswbb734.tar

[root@cams-a tools]# tar xvf oswbb734.tar

5.刪除osw

rm -rf oswbb

6.啟動與停止

arg1：快照時間間隔，以秒為單位

arg2：資料儲存最長時間

arg3：（可選）對資料進行壓縮的方法

arg4：（可選）資料儲存路徑

例子1：預設每30秒執行一次，儲存48小時

./startOSWbb.sh

例子2：每60秒執行一次，儲存10小時，自動壓縮

./startOSWbb.sh 60 10 gzip

例子3：每60秒執行一次，儲存10小時，自動壓縮，儲存至非預設路徑

./startOSWbb.sh 60 10 gzip /u02/tools/oswbb/archive

例子4：每60秒執行一次，儲存48小時，不壓縮，儲存至非預設路徑

./startOSWbb.sh 60 48 NONE /u02/tools/oswbb/archive

例子5：後臺執行，每60秒執行一次，儲存10小時

nohup ./startOSWbb.sh 60 10 &

停止：./stopOSWbb.sh

7.生成採集資料

當啟動osw後，在安裝目錄下會生成各種工具採集資料的子目錄。

資料檔案的格式為：

<node_name>_<OS_utility>_YY.MM.DD.HH24.dat

[root@cams-a oswbb]# nohup ./startOSWbb.sh 30 24 &

[1] 72749

[root@cams-a oswbb]# nohup: 忽略輸入並把輸出追加到"nohup.out"

[1]+ Done nohup ./startOSWbb.sh 30 24

[root@cams-a oswbb]# ls

analysis call_sar.sh Example_extras.txt ifconfigsub.sh ltop.sh nohup.out oswbba.jar oswrds.sh psmemsub.sh stopOSWbb.sh tmp

archive call_uptime.sh Exampleprivate.net iosub.sh mpsub.sh OSWatcherFM.sh oswib.sh oswsub.sh src tarupfiles.sh vmsub.sh

call_du.sh docs gif locks nfssub.sh OSWatcher.sh oswnet.sh profile startOSWbb.sh tar_up_partial_archive.sh xtop.sh

[root@cams-a oswbb]# ls archive/

oswifconfig oswiostat oswmeminfo oswmpstat oswnetstat oswprvtnet oswps oswslabinfo oswtop oswvmstat

[root@cams-a oswbb]# ls -l archive/oswmeminfo/

總用量 4

-rw-r--r--. 1 root root 2410 9月 2 21:42 cams-a_meminfo_16.09.02.2100.dat

8.生成取樣圖表

我們使用 OSWbba (Black Box Analyzer)工具對生成資料進行分析。

首先需要保證Java版本高於1.4.2

[root@cams-a ~]# java -version

java version "1.6.0_45"

Java(TM) SE Runtime Environment (build 1.6.0_45-b06)

Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)

假定將圖表生成在archive檔案路徑下（也可選擇其他路徑）

[root@cams-a oswbb]# java -jar oswbba.jar -i archive

9.私有網路

如需監控私有網路，可修改Exampleprivate.net檔案內容，將<node1-priv>換成主機名，並修改檔名為private.net後重啟即可

10.說明

osw工具可以收集歷史資訊，可以對特定時間端的資料進行回放，但是要注意，其收集資訊會因

取樣間隔較短而變得很大，因此需要關注archive目錄的空間。

收集的資訊對於整體的資源使用情況，有比較直觀的顯示效果。

附：生成報表命令引數

-i <archive dir> Required.This is the input archive directory location.

-6 Same as option 6 from the menu. Will generate all disk gif files.

-7 Same as option 7 from the menu. Will generate all cpu gif files.

-8 Same as option 8 from the menu. Will generate all memory gif files.

-L <location name> User specified location of an existing directory to place any gif files generated by OSWbba. This overrides the OSWbba automatic convention for placing all gif files in the /gif directory. This directory must pre-exist!

-A <analysis name> Same as option A above. This option analyzes the files in the archive directory and produces a report

-S <analysis name> Same as option S above. This option analyzes a specific subset of times of the files in the archive directory and produces a report. This option is used together with the -B and -E options

-START <filename>Used with the analysis option to specify the first file located in the oswvmstat directory to analyze.

-STOP <filename>Used with the analysis option to specify the last file located in the oswvmstat directory to analyze.

-P <profile name> User specified name of the html profile generated by OSWbba. This overrides the oswbba automatic naming

-NO_NETSTAT <filename> Ignores files in the oswnetstat directory from analysis.

-NO_LINUX <filename> Ignores files in the oswmeminfo directory from analysis.

-MEM_ALL <filename> Analyzes virtual and resident memory allocation for all processes. This is very resource intensive.

For Example：

java -jar oswbba.jar -i archive/ -6 -7 -8 -P 20160903_crash

我們也可以透過參考OSW工具中的shell指令碼，自行改造，適應成自己作業系統所需的指令碼。
OSW不只是用於監控資料庫伺服器，還可以監控應用伺服器等。
