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
I also get false alerts cpu is 1% check alert

NAME
tempfile - create a temporary file in a safe manner SYNOPSIS
tempfile [-d DIR] [-p STRING] [-s STRING] [-m MODE] [-n FILE] [--directory=DIR] [--prefix=STRING] [--suffix=STRING] [--mode=MODE] [--name=FILE] [--help] [--version] DESCRIPTION
tempfile creates a temporary file in a safe manner. It uses tempnam(3) to choose the name and opens it with O_RDWR | O_CREAT | O_EXCL. The filename is printed on standard output. See tempnam(3) for the actual steps involved in directory selection. The directory in which to create the file might be searched for in this order (but refer to tempnam(3) for authoritative answers): a) In case the environment variable TMPDIR exists and contains the name of an appropriate directory, that is used. b) Otherwise, if the --directory argument is specified and appropriate, it is used. c) Otherwise, P_tmpdir (as defined in <stdio.h>) is used when appropriate. d) Finally an implementation-defined directory (/tmp) may be used. OPTIONS
-d, --directory DIR Place the file in DIR. -m, --mode MODE Open the file with MODE instead of 0600. -n, --name FILE Use FILE for the name instead of tempnam(3). The options -d, -p, and -s are ignored if this option is given. -p, --prefix STRING Use up to five letters of STRING to generate the name. -s, --suffix STRING Generate the file with STRING as the suffix. --help Print a usage message on standard output and exit successfully. --version Print version information on standard output and exit successfully. RETURN VALUES
An exit status of 0 means the temporary file was created successfully. Any other exit status indicates an error. BUGS
Exclusive creation is not guaranteed when creating files on NFS partitions. tempfile cannot make temporary directories. tempfile is dep- recated; you should use mktemp(1) instead. EXAMPLE
#!/bin/sh #[...] t=$(tempfile) || exit trap "rm -f -- '$t'" EXIT #[...] rm -f -- "$t" trap - EXIT exit SEE ALSO
