Hi,

Try using a interval:
# sar -A 3

Kind regards,

Hi ,

sa27 is the binary file for date 27. Check your system date whether is proper.

It seems thats you dont have today's file in that directory. So check the system's date , it is 28. Then do this,

#cd /var/log/sa/
#sar 1 10 -o sa28
wait few secs and press control+c .

Now give.

#sar -A

Now the command should work. Give the command after 30 min and 1 hour to see the cummulative reports.

regards,

U.SivaKumar

I'm attaching some adaptable sar scripts that might collect some data for you.

You will need to fix some hp-ux related errors, but its not so bad.

First of all check the sysstat in /etc/cron.d/
Your /etc/cron.d/sysstat should read this

*/1 * * * * root /usr/lib/sa/sa1 1 1

53 23 * * * root /usr/lib/sa/sa2 -A

If it does already, then I am sure you dont have /usr/lib/sa. Create sa in /usr/lib/ and wait for a few minutes. Sar will dance to your tunes.

try running the sar -A with an interval of your choosing and you will get the out put you are searching,just using it alone will give you the error that you received.


I tried it to and got the same error mesg with sar -A but using sar -A 4 gave me an output.
