Step 3:  Starting oswbb service;

[root@isupdbsh oswbb]# ./startOSWbb.sh

from now, os watcher will gather any information about System Memory,System CPU Utilization,System I/O etc...

there are some folders,which are important to find out whats going on operating system, under oswbb directory . these folders are: analysis,profile and archive;

Step 4: How to create profile and save  as html;

[oracle@isupdbsh oswbb]$ java -jar oswbba.jar -i archive -6 -7 -8 -P crash -L /opt/oswbb/gif/ -B DEC 06 10:00:00 2012 -E DEC 06 11:00:00 2012

parameters:

 -i : <archive dir> Required. This is the input archive directory location. 
 -6 : Will generate all cpu gif files. 
 -7 : Will generate all memory gif files. 
 -8 : Will generate all disk gif files. 
 -P :User specified name of the html profile generated by OSWg 
 -L : User specified location of an existing directory to place any gif files generated by OSWg 
 -B :The start time will allow the user to select a start time from within the archive of files to graph/profile 
-E : The end time will allow the user to select an end time from within the archive of files to graph/profile

Now check profile folder under oswbb and inside crash folder open OSW_profile.htm and also os watcher generates gifs information about operating system between 06.12.2012 10:00:00 and 06.12.2012:11:00.

and also check /opt/oswbb/analysis folder to get some usefull information about cpu,memory, I/O,Net.

when u check these folders under /opt/oswbb/archive/, there are many files with .data extension and each folders hold information about operating system.U can check these .data files(Example of file under each folders : isupdbsh_netstat_12.12.06.1100.dat).

P.s : If u want to change SnapshotInterval  and  ArchiveInterval then u need to start service like the below command;

./startOSWbb.sh ARG1 ARG2;

ARG1 : snapshot interval in seconds (default 30 seconds). ARG2:  the number of hours of archive data to store (default 48 hours)
