I need overall load for all processes.

For overall load - Need to remove the process name.. Thats all
top -b -n 1 -d 1.0 |grep -e "^Cpu" |awk {'print $2'} | tr "%us," " " > cpu_file.log

I am using this one check:

    top -b -n 10 -d 0.0 | grep -e "^Cpu" | tr "," " " | grep -e "%id" | awk {'print 100-$5'} | sort -rn | head -1
