script to alert mount point space status without mail alert

This script is used to check the mount points space status without mail alert. Save the mount points name in mn.log file before running this script.

#!/bin/bash
rm mn1.log
rm diff.log
df -h |awk ‘{print $6}’|grep -v Mounted >>mn1.log
comm -13 mn.log mn1.log 1>>diff.log 2>/dev/null
if [ ! -s diff.log ]

then

for ml in `cat mn.log`

do

usedSpc=`(echo $(df -h $ml|awk ‘{print $5}’|grep -v capacity|cut -d “%” -f1 -))`
case $usedSpc in
[7-8][5-9])
diskStatus=”SPACE GETTING LOW AT MOUNT POINT: $ml —— :$usedSpc%”
echo -e “\e[1;32m $diskStatus \e[0m” >>mntst.log
;;
[9][0-8])
diskStatus=”WARNING, RUNNING OUT OF SPACE AT MOUNT POINT: $ml —— :capacity $usedSpc%”
echo -e “\e[1;31m $diskStatus \e[0m” >>mntst.log
;;
[1][0][0])
diskStatus=”MOUNT POINT FULL.. NO SPACE LEFT AT MOUNT POINT: $ml —— : $usedSpc%”
echo -e “\e[1;31m $diskStatus \e[0m” >>mntst.log
;;

done

else
echo -e “\e[1;31m MOUNT POINT MISSING : `comm -13 mn.log mn1.log` \e[0m” >>mntst.log
