File Name : cpumemdisk.sh

#/bin/bash
echo “This system date  is $(date)”
echo ”                                                           “;
echo “Load Report in the Server:-“;echo “———————————–“;sar -q | tail -n +4 | grep -v -average | awk {‘print $5 ” ” $1’}| sort -rn | awk {‘print “Time: ” $2 ” %Load: “$1’} | head
echo ”                                                           “;
echo “Memory Usage Report in the Server:-“;echo “———————————–“;sar -r | tail -n +4 | grep -v -average | awk {‘print $5 ” ” $1’}| sort -rn | awk {‘print “Time: ” $2 ” %Memory used: “$1’} | head
