CPU performance 2

[AIXUser53]

Hi all,

What is the best way to capture CPU Performance trough out the day and save it in a log file. I have been using
ps aux , but it can only capture once. I don't know how to set the command to capture like every 5 minutes.

Any Idea would be helpful

Thank you in Advance.

Using `sar` would be the best choice for your activity. Using `ps` you would have to write a script to sleep for 5 minutes and loop.

The only reason I want to use ps command is to check to see which user at what time processing and usign how much % of the CPU.

while true
do
ps aux > /tmp/filename
sleep 300
done

This will continue until you break (Cntrl-C).

Actualy,

while true
do
ps aux >> /tmp/filename
sleep 300
done

Otherwise you overwrite the file each time,instead of accumulating data.

"nmon" tool would be usefull,can collect info to logs as well.

And possibly place the above script in your crontab so that it runs every five minutes:

00,05,10,15,20,25,30,35,40,45,50,55 * * * 0-6 <script>

Bear in mind, though that this will produce quite a lot of data and you might wish to periodically zap the log file to avoid it getting too large. HTH.

you can try vmstat also... It is also a goot command to analyize CPU Utillization
