@dinjo_jo
the only command that i know before to show process only top that why i only used it Smilie

i have question about this :
Code:
DOMAIN=`uname -n`
usage=`top | grep idle | cut -c 13-14`
 if [ $usage -le 40 ] ; then 
  echo "$DOMAIN Normal $usage%"
 elif [ $usage -ge 50 && $usage2 -le 65 ] ; then
   echo "$DOMAIN Warning $usage%"      
 elif [ $usage -ge 66 && $usage2 -le 80 ] ; then
   echo "$DOMAIN Major $usage%"
 elif [ $usage -gt 80 ] ; then       
  echo "$DOMAIN Critical $usage%"   
 fi

but always said like this :
Code:
./test2: line 7: [: missing `]'
./test2: line 9: [: missing `]'
