CPU and Memory Reports HP UX

Hi Friends,

To find detailed view and reports of CPU, memory, disk utilization, file system usage, application, disk io, swap etc. there is very good utility in HP UX. I did it in HP UX 11.31, not aware of other  version. need to check more on it.

EXTRACT utilty, which is making use of scopeux behind is very good extract utility. It can bring out report of more than a month. 

Reading man page of extract can help you to choose multiple option for individual CPU or other parameter. We used the global option which brings detailed report. U can extract the same data in excel sheet and choose according to your requirement. And create graphs for your monthly report. 

€ the configuration file for export is in /var/opt/perf/Parms 

€ the services which need to be restarted  are
#/opt/perf/bin/perfstat :- command to check the o/p of performance status
#/sbin/init.d/ovpa stop
# /sbin/init.d/ovpa start

The command to take out report one month is :-


#extract -xp -g -b today-30 -e today -f /tmp/reports.out --  to bring out 30 days report from current date.

#/usr/bin/uuencode /tmp/reports.out /tmp/reports.out |mailx -m -s "mem1" xyz@xyz.com

(using above command you can mail yourself the reports.out file or any attachment/file..)

would like to show how the o/p of data in graph format can be viewed in excel sheet after it is extracted on excel sheet.

CPU :-

similarly Memory, File system usage, etc reports can be taken out.

We are help less

Physical wall of Germany broken but still we can see some differences.

We became independent but still we are slave with our mentality. We still need to work on it. 

Religions are free to be chosen but still we are lacking in our thoughts to accept one. 

Millions roads are built in this world but we are bounded by borders. 

Thoughts are like oceans but very less of them are positive.

......

Want to post more on it.
