Error while running a script through cron job

Hi Team,

When i am running the below query manually it is giving me the right output
i.e.

Code:

export PATH=/usr/sbin:/usr/bin:/sbin:/bin:$PATH
ADMIN=abc@abc.com
CPU_HIGH=`sar|awk '{print $9}'|sort -n|head -5|sed -n 5p`
CPU_MAX=`echo "scale=3; 100-$CPU_HIGH" | bc`
CPU_LOW=`sar|awk '{print $9}'|sort -n|tail -1`
CPU_MIN=`echo "scale=3; 100-$CPU_LOW" | bc`
MEM_MAX=`cat /root/admin_files/server_monitor/datewise_monitor/ram_monitor-$(date +"%d-%B-%Y")|awk '{print $2'}|sort -n|tail -1`
MEM_MIN=`cat /root/admin_files/server_monitor/datewise_monitor/ram_monitor-$(date +"%d-%B-%Y")|awk '{print $2'}|sort -n|head -1`
now=`date +-%Y-%m-%d-%H:%M:%S`
file=utilization_$now.log
filename=/root/admin_files/server_monitor/datewise_monitor/$file
echo "$(date): Memory Utilization Report for server $(hostname) is" >>$filename
echo "-----------------------------------" >>$filename
echo "                                   " >>$filename
echo "CPU Max Utilization :  $CPU_MAX %  " >>$filename
echo "CPU Min Utilization  :  $CPU_MIN % " >>$filename
echo "                                   " >>$filename
echo "Max Ram Utilization :  $MEM_MAX %  " >>$filename
echo "Min Ram Utilization  :  $MEM_MIN % " >>$filename
cat $filename| mail -s "$(date +"%d-%B-%Y"): CPU & Memory Summarization Report for server $(hostname) : "$(ifconfig eth0 | sed -n '/inet /{s/.*addr://;s/ .*//;p}')" " $ADMIN
sar >> /root/admin_files/server_monitor/datewise_monitor/cpu_monitor$(date +"-%d-%B-%Y").txt
sar -r >>/root/admin_files/server_monitor/datewise_monitor/memory_monitor$(date +"-%d-%B-%Y").txt

Output:

Code:

Mon Mar 17 14:47:28 GMT 2014: Memory Utilization Report for server mmv0pfecdel0070 is
  -----------------------------------
                                     
  CPU Max Utilization :  7.29 %  
  CPU Min Utilization  :  .07 % 
                                     
  Max Ram Utilization :  12.000 %  
  Min Ram Utilization  :  11.800 %

But when i am running the script through cronjob it is giving me the below output:

Code:

 Mon Mar 17 15:02:01 GMT 2014: Memory Utilization Report for server mmv0pfecdel0070 is
  -----------------------------------
                                     
  CPU Max Utilization :   %  
  CPU Min Utilization  :   % 
                                     
  Max Ram Utilization :  12.000 %  
  Min Ram Utilization  :  11.800 %

Please assist me in this.
