Code:
#!/bin/sh
# Script to send email alerts to mail box if cpu is more than 90% utilization
LIMIT=90
ALERT="monitoringbox@abc.com"
TEMPFILE=/tmp/temp1
HOSTNAME=`hostname`
rm -f $TEMPFILE
CPU_LOAD=`sar -P ALL 10 1 |grep Average' |awk -F" " '{print 100.0 -$NF}' |cut -d \. -f1`
if [[ $CPU_LOAD -gt $LIMIT ]];
then
echo "CPU is high on $HOSTNAME " >> $TEMPFILE
fi
if [ -e $TEMPFILE ]
then
mail -s " CPU ALERT  " $ALERT < $TEMPFILE
fi
rm -f $TEMPFILE


The above script is working as desired , ran from crontab for every 5 minutes

NAME

       cpu - A tool for user and group administration

SYNOPSIS

       cpu [OPTIONS]

DESCRIPTION

       CPU is a tool for user administration, that was initially based on FreeBSD's pw(8). This tool will allow you to administer users and groups
       on several different backends currently including LDAP and flat files. Please see the website http://cpu.sourceforge.net for more  informa-
       tion, or help improve the man page.

OPTIONS

       There are two kinds of options; options for CPU and options for CPU modules.  There are only four options for CPU, they are as follows:

       -C configfile, --config configfile
	      The configuration file to be used by CPU. The options in this file are used for CPU modules.

       -h, --help
	      Display help for CPU. If specified in conjunction with the -m option the help for that particular module is displayed.

       -M method, --method=method
	      This  is	the method of administration. Current options are ldap or passwd (passwd is not yet working). This can be specified in the
	      configuration file.

       -V, --version
	      Display the version of the software.
