Oracle OSWatcher tool and yast for EM Grid Control

 

These days I configured Oracle OSWatcher tool and yast package for EM Grid Control used to manage and monitor Oracle servers. I want to share how quickly to configure and start using them on Linux.

 

 

OSWatcher invokes system utilities like ps, top, iostat, vmstat, netstat and collects data according to the specified parameters. You can download it from Metalink.

unzip it to OSWatcher directory you would use($OSWATCHER_HOME)

tar -xvf oswbb4.0.tar

 

 

OSWatcher has been renamed to OSWatcher Black Box to avoid the confusion with the too many tools with this name. OSWatcher Black Box Analyzer(OSWbba ) is a graphing and analysis utility which comes bundled with OSWbb v4.0.0 and higher. For OSWbba you need java version 1.4.2 or higher.

Put next lines in the profile needed by OSWatcher:

export JAVA_HOME=$ORACLE_HOME/jdk/jre
export PATH=$JAVA_HOME/bin:$PATH
alias oswatch=’java -jar $OSWATCHER_HOME/oswbba.jar -i $OSWATCHER_HOME/archive’

 

 

Let’s start it with nohup in background and configure to take snapshots with the system utilities at every 5 minutes for the last 24 hours.

nohup ./startOSWbb.sh 300 24 &

 

What it does is subdirs in $OSWATCHER_HOME/archives like oswiostat, oswmeminfo, oswmpstat, oswnetstat, oswprvtnet, oswps, oswslabinfo, oswtop, oswvmstat where result .dat files with collected data for each hour reside. OSWbba parses all the archive files and you invoke it from the alias created in the profile:

$ oswatch

Yast(Yet Another Setup Tool) is needed if you need to administer a linux host through Enterprise Manager Grid Control. Download yast from here.

tar -xvf yast_el5_x86_64.tar
cd yast_el5_x86_64
./install.sh

 

Start it in the commandline:

/sbin/yast

 

 

 

 

 

Here is how it looks like in EM Grid Control:

    hi. only recently i use OSwatcher using “nohup ./OSWbb.sh 600 7″ expecting the script to finish after 7 hours. when i checked the archive directory (and the nohup.out) file, it’s still running after 12 hours!

    did i understood the docs wrong?

    appreciate any help.

    Hi,

    With your configuration it should take snaphots at every 10 minutes for the last 7 hours. It will not stop running after 7 hours. The result files will be overwritten.

    Regards,
    Maria
