Problem with sar command in cron job
HI,
I have a problem with 'sar' command.
I am using the sar comman in script.when i execute the script manually using ./filenae, i am getting the desired output.
But when i put the script in cron job i am not getting the desired value.

Below is the script..

Code:
sar > $_LOCATION/sar.txt
_IDLETIME=`tail -2 $_LOCATION/sar.txt | head -1 | tr -s ' ' ' ' | cut -d ' ' -f8 | cut -d '.' -f1`;
echo "Hi $_IDLETIME"
if [ $_IDLETIME -ge 60 ]
  echo $_IDLETIME
else
  echo "XXXX"
fi

what might be the cause of this issue.

Thanks,
Ahamed.

sa2

SA2(8)								Linux User's Manual							    SA2(8)

NAME

       sa2 - Write a daily report in the /var/log/sa directory.

SYNOPSIS

       /usr/lib64/sa/sa2

DESCRIPTION

       The  sa2  command  is  a shell procedure variant of the sar command which writes a daily report in the /var/log/sa/sardd file, where the dd
       parameter indicates the current day. The sa2 command handles all of the flags and parameters of the sar command.

       The sa2 command is designed to be started automatically by the cron command.

EXAMPLES

       To run the sa2 command daily, place the following entry in your root or adm crontab file:

       5 19 * * 1-5 /usr/lib64/sa/sa2 -A &

       This will generate a daily report called /var/log/sa/sardd It will also remove reports more than one week old.

FILES

       /var/log/sa/sardd
	      Indicate the daily report file, where the dd parameter is a number representing the day of the month.
