OSWATCHER is an oracle utility used to capture performance metrics from the operating system. We can get it easily from oracle website, and it doesnt need additional license.
In this article, we will show ,how to install oswatcher utility and its application.
1. Download oswatcher from oracle support.
2. Copy and untar the file :
/archive/OSWATCHER# pwd /archive/OSWATCHER /archive/OSWATCHER# ls -ltr total 12557 -rw-r--r-- 1 oracle oinstall 6318080 Jul 31 2016 oswbb734.tar
/archive/OSWATCHER# tar -xvf oswbb734.tar x oswbb, 0 bytes, 0 tape blocks x oswbb/call_uptime.sh, 71 bytes, 1 tape blocks x oswbb/profile, 0 bytes, 0 tape blocks x oswbb/analysis, 0 bytes, 0 tape blocks x oswbb/tar_up_partial_archive.sh, 4219 bytes, 9 tape blocks x oswbb/oswsub.sh, 524 bytes, 2 tape blocks x oswbb/oswrds.sh, 825 bytes, 2 tape blocks x oswbb/src, 0 bytes, 0 tape blocks x oswbb/src/missing_graphic.gif, 8694 bytes, 17 tape blocks x oswbb/src/tombody.gif, 4175 bytes, 9 tape blocks x oswbb/src/coe_logo.gif, 2994 bytes, 6 tape blocks x oswbb/src/Thumbs.db, 10240 bytes, 20 tape blocks x oswbb/src/OSW_profile.htm, 26288 bytes, 52 tape blocks x oswbb/src/oswbba_input.txt, 135 bytes, 1 tape blocks x oswbb/src/watch.gif, 5621 bytes, 11 tape blocks x oswbb/oswib.sh, 414 bytes, 1 tape blocks x oswbb/call_du.sh, 67 bytes, 1 tape blocks x oswbb/tarupfiles.sh, 746 bytes, 2 tape blocks x oswbb/ltop.sh, 1486 bytes, 3 tape blocks x oswbb/nfssub.sh, 740 bytes, 2 tape blocks x oswbb/docs, 0 bytes, 0 tape blocks x oswbb/docs/OSWatcher, 0 bytes, 0 tape blocks x oswbb/docs/OSWatcher/OSWatcherUserGuide.pdf, 3531131 bytes, 6897 tape blocks x oswbb/docs/OSWatcher/oswbb_README.txt, 14309 bytes, 28 tape blocks x oswbb/docs/The_Analyzer, 0 bytes, 0 tape blocks x oswbb/docs/The_Analyzer/oswbba_README.txt, 28319 bytes, 56 tape blocks x oswbb/docs/The_Analyzer/oswbbaUserGuide.pdf, 1959618 bytes, 3828 tape blocks x oswbb/docs/The_Analyzer/OSWatcherAnalyzerOverview.pdf, 393822 bytes, 770 tape blocks x oswbb/OSWatcher.sh, 35108 bytes, 69 tape blocks x oswbb/psmemsub.sh, 1445 bytes, 3 tape blocks x oswbb/call_sar.sh, 68 bytes, 1 tape blocks x oswbb/oswnet.sh, 435 bytes, 1 tape blocks x oswbb/Exampleprivate.net, 1864 bytes, 4 tape blocks x oswbb/mpsub.sh, 542 bytes, 2 tape blocks x oswbb/Example_extras.txt, 626 bytes, 2 tape blocks x oswbb/OSWatcherFM.sh, 5062 bytes, 10 tape blocks x oswbb/startOSWbb.sh, 2574 bytes, 6 tape blocks x oswbb/ifconfigsub.sh, 772 bytes, 2 tape blocks x oswbb/iosub.sh, 743 bytes, 2 tape blocks x oswbb/oswbba.jar, 233897 bytes, 457 tape blocks x oswbb/vmsub.sh, 545 bytes, 2 tape blocks x oswbb/xtop.sh, 1486 bytes, 3 tape blocks x oswbb/stopOSWbb.sh, 558 bytes, 2 tape blocks
3. Start the oswatcher in background.
nohup ./startOSWbb.sh 30 168 &
30 – > Means snapshot interval in seconds.
168 -> the number of hours of archive data to store
4. Validate whether oswatcher is running or not
/archive/OSWATCHER/oswbb# ps -ef | grep oswbb oracle 22475 22221 0 15:13:24 pts/1 0:00 /bin/sh ./OSWatcherFM.sh 168 /archive/OSWATCHER/oswbb/archive oracle 23164 14751 0 15:14:38 pts/1 0:00 grep oswbb diagostic data will be generated under archive directory /archive/OSWATCHER/oswbb/archive# ls -ltr total 24 drwxr-xr-x 2 oracle oinstall 2 Nov 23 15:12 oswprvtnet drwxr-xr-x 2 oracle oinstall 2 Nov 23 15:12 oswifconfig drwxr-xr-x 2 oracle oinstall 3 Nov 23 15:13 oswvmstat drwxr-xr-x 2 oracle oinstall 3 Nov 23 15:13 oswmpstat drwxr-xr-x 2 oracle oinstall 3 Nov 23 15:13 oswnetstat drwxr-xr-x 2 oracle oinstall 3 Nov 23 15:13 oswiostat drwxr-xr-x 2 oracle oinstall 3 Nov 23 15:13 oswtop drwxr-xr-x 2 oracle oinstall 3 Nov 23 15:13 oswps
6. Generate graphs for CPUs and memory usage from oswatcher files.
We can generate graphs for CPU and memory and disk io statistics from the oswatcher collected files for a particular time period. Make sure the oswatcher files exists for that timeframe.
