if there is o warning yellow or red, the SENDMAIL variable is not defined and this gives a sintaxis error in the eval:
if [ $SENDMAIL -ge 1 ]; then

So the better way to avoid this error is change the test as follows:

if [ ! $SENDMAIL ]; then
# SENDMAIL is not defined, so there is no warning
else
#Put here the sending mail procedure
….

fi

To be able to send a mail only when there is a YELLOW or a RED warning you should modify the script as follows:

SENDMAIL=0
SENDMAIL=$( /usr/sbin/vdf -h -P | sort -k 6 | grep -E ‘^/vmfs/volumes/’ | awk ‘{ print $2 ” ” $3 ” ” $4 ” ” $5 ” ” $6 }’ | while read output ; do
……
……
if [ $CUTPERC -ge $VMFSYELLOW ] ; then
WARNING=”yellow”
echo -ne 1
fi
……
……
done
)
echo “” >> “${LOG}”
echo “VMFS – Disk Usage Monitor by BitBat, S.L.” >> “${LOG}”
echo “” >> “${LOG}”
echo “” >> “${LOG}”

if [ $SENDMAIL -ge 1 ]; then
MAIL_BODY=`cat ${LOG}`

/usr/bin/perl smtp_send.pl -t $MAIL_TO -f $MAIL_FROM -s “VMFS Disk Usage – $MYDATE” -r $MAIL_SERVER -m “$MAIL_BODY”
fi

how did you modify the script?
I need the same functionality, I want only Emails when one of the Volumes status is red. could you help me ?

Thank you

Naz

thanks for the nice script. I’ve got a ESX 3.5 Server and it works great. I modified it so it only sends Emails when one of the Volumes status is “red”. Manually used it works perfect, but when I put it in Crontab as a job nothing happens. In the Crontab log files I can see that the script is executed every hour, thats like i wanted it but theres no email sending… can you help me? Thanks for help greetings from germany

thanks for your very great script. Your Script works very good. I am a beginner in perl but now I would like to modify the script. I would like to be Informed only if the threshold for Warning is reached.

at the bottom of your script,I have add this.

if [ $CUTPERC -ge $VMFSRED ] ; then
/usr/local/bin/smtp_send.pl -t info@me.com -s “Diskspace report of the VMFS volumes” -f esx01@me.com -m “`cat /var/log/vdf.html`” -r 172.10.10.10
fi

But unfortunately it does not work because the values of $CUTPERC and $VMFSRED are lost after the loop. Could you give me a hint , how I can solve my problem

Many thanks.

very great job! This script is very useful.
Thanks a lot !
