Hi

I run the glance command to check CPU utilization there I got CPU utilization as follows Current=7% Average=21% and High=100%.Is there any command or tool from which we can check for which perticular process it got 100% .I want to check this 100% even after one day also.

Regards
Vishal

Hi

You can use top command or sar utility.

Refer the man pages of sar and top.

Hi Vishal,
you can use perfview to analyse the historical data - glance is just for real time analyses.

Hi,

You need OVPA, perfview to get the historical data. OVPA will work with glance to store the historical data.

Top, sar, glance will not give you the historical data.

sar can be set in crontab and the saved file will be kept in /var/adm/sa. For example:

0,10,20,30,40,50 * * * * /usr/lib/sa/sa1
45 23 * * 1-5 /usr/lib/sa/sa2 -i 1200 -A

You can just view the files in /var/adm/sa which has the info of cpu for last 30 days.

No need to use another utility. Run glance, then press the letter o (that's lowercase o) and press return to select the first option: 1) process. You will now see a table that allows you to filter only interesting processes. I typically fill in the form with CPU = 10, disk = 50, RSS=300, VSS=500, user,program,TTY set to all, match=or and sort by cpu. Then Perform Task (if you have softkeys on your terminal, or press return until it goes back to the main screen. Now the heaviest CPU load will be at the top of the list.

Hint: While glance is running, press the ? character. It shows you all the shortcut keys like d for disk or l for lan or i for filesystem I/O.

Glance is a real time display and always shows what is happening now. However, in the background, there are logs kept in /var/opt/perf which contains records for several days. You must run the extract program to find the options you need to see CPU usage at a particular date and time. Use the command: man extract to see the options.
