sar

[R_77]

Trying to run sar -M

Getting the following error:

sar: Can't open /var/adm/sa/sa07

How to fix?

Thanks

Run it sar -M X Y, where X is number of seconds beetwen samples, Y is the number of samples.

Anyway, read the manual: man sar

Hi R,

Check the directory /var/adm/sa

# ls
sa01 sa04 sa07 sa10 sa13 sa16 sa19 sa22 sa25 sa28 sa31
sa02 sa05 sa08 sa11 sa14 sa17 sa20 sa23 sa26 sa29
sa03 sa06 sa09 sa12 sa15 sa18 sa21 sa24 sa27 sa30

check the sys crontab
# crontab -l sys
#
# -- SAR History Information
#
0,5,10,15,20,25,30,35,40,45,50,55 * * * 0-6 /usr/lib/sa/sa1

Hi:

See the manpages for 'sar". You don't have a daily activity file for today ("sa07").

If you want to look at CPU queues in real time, and examine the per-processor statistics, then you could do:

# sar -Mq 3 10

...which would report CPU queues for every processor every 3-seonds for 10-iterations.

Regards!

Setup sar:

In root's cron, setup something like:

# SAR0 * * * * /usr/lib/sa/sa1
10,20,30,40,50 5-19 * * * /usr/lib/sa/sa1
# reduce the sar data
5 19 * * * /usr/lib/sa/sa2 -s 5:00 -e 19:01 -i 600 -A

Make sure the directory /var/adm/sa exists

Hi,

As the sar is not setup/configured, you may run

#sar -u

ie,

#sar -u 1 5

to get the CPU utilization.

similarly you can use the other options to get the activity of different resources.

With Regards,

Siva.

mkdir /var/adm/sa
mkdir /var/adm/sa/sa07

[Muthukumar_5]

You have to interval and count to run sar with our having directory called /var/adm/sa/.

Like this,

# sar -M 5 5
