Hi Ritesh,

Run the below script in all server and change the email id according to yours

#!/bin/bash

df -Ph | grep -v File | while read out
do

partuse=echo $out | awk '{print $5}' | cut -d'%' -f1
partdir=echo $out | awk '{print $6}'

     if [ $partuse -ge 70 ]
     then
        echo "Partition $partdir Usage is more $partuse%" | mail -s "Disk Usage More" test@example.com
     fi

done

Maybe this can help

Code:
awk ’ BEGIN {
“hostname” | getline host
recipient = “root”
threshold = “90%”
df = “/bin/df -k”
while ( ( df |getline line ) > 0 ) {
split(line,array," “)
if (array[5] > threshold && array[5] !~ /[a-zA-Z]/) {
email=”/usr/bin/mail "recipient
print "Filesystem " array[1] " hits the threshold " threshold ".Value: " array[5] | email
close(email)
}
}
close(df)
}’
