Script abt Filesystem alert

[telenor]

AOA,

I made a following script that check filesystem, if any filesystem exceed to 90% then riase an alert only 1 time, but following script generate an alert every 5 minutes according to cronjob. so i need a correction on the script.

************************************************
ALERT="90"
ALERT1="85"
DFH="/tmp/dfout"
DFM="/tmp/dfmail"
CHK="/tmp/hdsize-chk"

rm -f $DFM

clear
echo

echo `date` | tee $DFM
echo | tee -a $DFM

df -h > $DFH
cat $DFH | grep -vE '^Filesystem|tmpfs|cdrom' | awk '{ print $5 " " $6 }' | while read output;

do
#echo $output
USEP=$(echo $output | awk '{ print $1}' | cut -d'%' -f1 )
FS=$(echo $output | awk '{ print $2 }' )
if [ $USEP -gt $ALERT ]
then
echo "Running out of space \"$FS - ($USEP%)\"" | tee -a $DFM
fi
done

if test -f $CHK
then
echo "Not Sending an Email"
exit

else

echo Sending an Email
$MAILPROG -s "$SUBJECT" "$EMAIL" < $DFM

echo Creating Tmp File
touch $CHK

fi

if [ $USEP -lt $ALERT1 ]
then
echo Removing Tmp File
rm -f $CHK

fi

AOA Azfar,


Here is my File System:

Filesystem Size Used Avail Use% Mounted on
/dev/sda1 20G 8.3G 11G 45% /
/dev/sda3 40G 33G 5.2G 87% /d01
none 3.9G 0 3.9G 0% /dev/shm
/dev/sdb 148G 113G 28G 81% /san
/dev/sdc 50G 9.0G 38G 20% /san01
/dev/sdd 403G 303G 79G 80% /san00

If any of the above filesystem exceed to 90% then riase an email alert only 1 time coz script will run with cronjob (after every 5 min).

[azfar]

here you go

Code: Select all

email="root"
mbody=/tmp/body
subject="Disk Usage Warning"
usage=`df -h /dev/sda1 /dev/sda3 /dev/sdb /dev/sdc /dev/sdd | awk 'NR==1{next}{ if ($5 > 90) print $6 " is at " $5;}'`
if [ -n "$usage" ]; then
echo "$usage" > $mbody
mail -s "$subject" "$email" < $mbody
fi

Dear Azfar,

Thanks for the Help.


If i run this script with crontab and file system is also exceed then this script raise an email alert every 5 minute.


Plz add something that raise an alert only 1 time not an every 5 minute.

[azfar]

dude the script just send an email alert (if the condition matched) whenever you run it, so you need to create an cron entry for any interval you want.
