Question on SAR

[lnxnoob]

Hi All,

I am setting up Linux SAR to record performance stats on my linux box.

I want to retain the data for 1 month.I changed the variable history to 31 days in /etc/sysconfig/sysstat and also on /usr/lib64/sa/sa2.

My question:

1. Since I set this only on october 30 and my SAR datafiles begin from october 17( previous datafiles were already removed) - will 31st day be only on november 17 or is it per calendar month like oct 1 - oct 31?


I am following this link ( FAQ 2.19)
<link > sebastien.godard.pagesperso-orange.fr/faq.html#sar < link>

Thanks in advance for the help.

it's per calendar days, there's nothing to worry about

Thanks you for the reply. But on the box I see this.According to the link I provided on the previous post, I should be seeing a folder <YYYYMM> and datafile <saDD>. But these files placed under /var/log/sa instead . I am a bit confused. Anything missing here?

How can I extract data using SAR in just a given time, like for example 03:00:00? Below is my syntax, but nothing comes out...

>sar -s 03:00:00 -e 03:00:01 -r | awk '{print $5}'

I plan to get the RAM used percentage...
