Resource report

[themuscle]

For an IT admin or someone running a small business it would be invaluable to have the ability to schedule a simple report showing the utilisation of your hard disks.

Resource Monitor already has a great looking window called "Disk Usage" we just need the ability to e-mail this in HTML based on a schedule.

The e-mail would just list the raid or virtual disk and then show Total, used and free disk space.

For qnap units that have very high traffic on a daily basis this would be a great addition.

Assuming that your SSMTP Server is properly configured, and you can successfully send test notification e-mails. The following script would do it for you.

(Note you will need to modify the SendTo, SendFrom, and (possibly Subject) variables at the top of the script

Code: Select all

#!/bin/sh
#
# nasnotify.sh - aka /share/homes/admin/bin/nasnotify.sh
# 
#  This script e-mails a report on the NAS / Drive Status to the designated recipient
#  See QNAP Forum article: http://forum.qnap.com/viewtopic.php?f=24&t=99093
# 
SendTo="me@somewhere.com"
SendFrom="TS-459@XXXXXX.myqnapcloud.com"
Subject="Resource Report from $(/bin/hostname)"
#
#
rm -f /tmp/nasreport.email
touch /tmp/nasreport.email
echo "From: ${SendFrom}"     >>/tmp/nasreport.email
echo "To: ${SendTo}"         >>/tmp/nasreport.email
echo "Subject: ${Subject}"   >>/tmp/nasreport.email
echo " "		     >>/tmp/nasreport.email


rm -f /tmp/nasreport
touch /tmp/nasreport
chmod +x /tmp/nasreport
cat <<EOF >>/tmp/nasreport

This isn't pretty, but it will get the job done without any MIME encoding, or HTML bloat. It's a simple text report, surely text is good enough for the e-mail message too to get the job done. Tested here. This script successfully delivered my NASReport output to my e-mail box. Simply save this script to somewhere on your NAS that will survive a reboot. (I created it at /share/homes/admin/bin/nasnotify.sh here)

If you save this script to the same location and make it executable, you can run if from the command line as often as you want.

Code: Select all

chmod +x /share/homes/admin/bin/nasnotify.sh

You can also make it run daily by adding it to the NAS Crontab file. If you wanted to run it at 3am every Sunday you can do this with the following commands:

Code: Select all

echo "0 3 * * 0 /share/homes/admin/bin/nasnotify.sh" >>/etc/config/crontab
#load Crontab changes...
crontab /etc/config/crontab
#restart Cron daemon to pickup the new item
/etc/init.d/crond.sh restart
#done

This is great, I will give it a try over the weekend.
Thanks for the reply.

Thanks for this Patrick.
I realized what a mess crontab is in after installing notestation.

This does not work for me. I receive "SENDMAIL: 550 5.6.0 Invalid header found (see RFC2822 section 3.6) Done. I can send a test email from the GUI control panel just fine so it's definitely in the script.

Unkless you have added some Mess-DOS CR/LF line terminators to the script ...

The key is that most SMTP handlers require a valid "From:" address - instead of the suggested ...

SendFrom="TS-459@XXXXXX.myqnapcloud.com"

...use your e-mail address configured for SMTP submission on the NAS.

It works:

I have done that, of course. I am using the exact same "from" and "to" addresses that I have setup in the gui. I can send test emails from the gui with no problem. I am using the smtp server from my isp which I use as a smtp relay server with all of my other devices perfectly fine. There is something in this script that the smtp server does not like.

[schumaku]

There is something in this script that the smtp server does not like.

Strongly doubt...

Change the sendmail (ssmtp) options from -t to -v -t near to the end:

old:

Code: Select all

cat /tmp/nasreport.email | sendmail -t

new:

Code: Select all

cat /tmp/nasreport.email | sendmail -v -t

..and now run the script again. Post the output (remove any sensitive AUTH data like usernames, paswords, or XOAUTH2 code. I'm glad to have an eye on your output.

Note: As per RFC2822 section 3.6 only two fields (plus the receiver address as a "To" obviously) are mandatory - marked bold in this example:
