OSWbb – How To Install And Configure OSWatcher Black Box For System Diagnostics

System troubleshooting is the major task for admin in day to day activities.

System admins are facing difficulties to identify system performance issue on Linux.

They can not able to figure it out what actually causing the issue. It is very hard to find the root cause.

There are many tools available in Linux to identify system performance issue but each tool (like top, vmstat, ps, iostat, etc) has it own features and we can’t get all in one place to identify the root causes.

Few tools are available in Linux to get all these details in one place. We already covered such kind of topic in past called sosreport.

What Is OSWatcher (OSWbb)

Oracle OSWatcher Black Box (OSWbb) collects and archives operating system and network metrics that you can use to diagnose performance issues. It’s a set of shell scripts OSWbb operates as a set of background processes on the server and gathers data on a regular basis, invoking below Unix utilities.

Make sure the blow packages should be installed on your system as prerequisites. If no, install missing packages using distribution package manager.

  • VMSTAT
  • IOSTAT
  • MPSTAT
  • IFCONFIG
  • NETSTAT
  • TOP
  • TRACEROUTE

oswbb is comprised of two separate components:

  • oswbb: a unix shell script data collector which collects and stores the data.
  • oswbba: a java utility which will analyze the data automatically and provide advice and produce graphs and an html document.

How To Install OSWatcher (OSWbb) In Linux

This is straight forward. Just download the latest available package version from oracle website and extract to descried location.

Move/Copy the file to the directory where you want to install OSWbb and extract the file.

# tar xvf oswbb812.tar

It creates a directory called oswbb, which contains all the directories and files that are associated with OSWbb.

# ls -lh /opt/oswbb

To start OSWbb, run the startOSWbb.sh script from the oswbb directory. This script accepts two parameters, which is Frequency & Duration.

  • Frequency : How frequent (in seconds) data needs to be collected.
  • Duration : How many hours data needs to be archived

If you do not input any arguments, the script runs with default values of 30 and 48. It collects data every 30 seconds and store the last 48 hours of data in archive files.

# ./startOSWbb.sh [Frequency Duration]

The below example collects and stores the last 10 hours of data to archive files at 60 second intervals.

# ./startOSWbb.sh 60 10
Setting the archive log directory to/opt/oswbb/archive

To stop OSWbb prematurely, run the stopOSWbb.sh script from the oswbb directory.

# ./stopOSWbb.sh

How To View The Collected Data

Collected data will be stored under archive directory, it is created when OSWbb is started for the first time. OSWbb stores data in hourly archive files named system_name_utility_name_timestamp.dat, and each entry in a file is preceded by the characters *** and a timestamp.

# ls -lh /opt/oswbb/archive

OSWatcher Analyzer

oswbba is a graphing and analysis utility which comes bundled with OSWatcher. This allows the user to graph and analyze data collected from running OSWatcher. Analyzing this data automatically avoids the time consuming task of manually inspecting all the files that OSWatcher collects. This utility is a stand-alone java program which requires java to be installed.

# java -jar oswbba.jar -i /opt/oswbb/archive/
