Email notification about UPS power supply

[nicko_mv]

I have tested this, and it works well, however there seems to be an issue where after the unit is restarted you get the 'NAS is back to normal' email - even though it wasnt shut down/restarted due to power - have you any ideas on how to make it only send the email after the NAS has been shut down previously by the UPS or woken by the UPS?

I have also tested this & its working. Thanks
There are a few side effects though:
1. As mentioned in the post above mine, an email is sent everytime the NAS is restarted.
2. The NAS restart time has increased due to the sleep commend at the end. I reduced it to 60 seconds from the 360 seconds in the script, but please tell me what is this sleep command for?

Any ideas??

The sleep command was needed for the next command which is used to send the mail UPS is back to normal, without the sleep it was inconsistent because the network was not active during the boot.
You can remove both the sleep and the mail commands if you don't want to receive a mail after each boot.

Do you want me to change it so that it will only send the mail UPS is back to normal after a forced shutdown event?

I dont mind the mail after every boot much...I was more concerned about the sleep thing. I have a synology 1010+ & it does start within 60 seconds so the mail is still sent even if I reduce this sleep to 60. Just wanted to reduce the restart time of the DS, if possible.
I guess this is good enough for me...until synology provides something similar officially
Thanks

It would be good to get a mail only after a forced shutdown event - in my case I have the emails forwarded to an email to SMS provider - which then forwards an sms to about 4 mobile numbers. Purpose is to monitor the mains power as we have a few power outages and need to crank up the backup generator. Would be good to only get the sms after a forced shutdown event as that way we know that its not just me rebooting the server

Thanks!

This is what you should do so that it will only send a mail after a forced shut down event.
At the end of /usr/syno/bin/synoups add the line in red:
fsd)
/usr/syno/bin/synomail UPSFSD
touch /usr/syno/ups_post_fsd
/usr/syno/sbin/upsmon -c fsd
UPSSafeMode $1
;;
esac

And on /usr/syno/etc.defaults/rc.d/S99UPSMail.sh add the lines in red:
#!/bin/sh

if [ "$1" = "start" ]
then
cp -p /usr/syno/etc/ups/upssched.conf.OK /usr/syno/etc/ups/upssched.conf

if [ -e /usr/syno/ups_post_fsd ]
then
rm -rf /usr/syno/ups_post_fsd
sleep 360
/usr/syno/bin/synomail UPSOnLineBoot
fi
fi

I'm not able to test it but I believe it should work.

DO we just append this to the files that we previously edited? Or do we have to remove any lines in order to take out the previous 'email sent on normal reboot' alert?
Thanks again for your help!

[quietsy]

Just append the lines in red to the files that were previously edited in the right locations.

So been running this for a while, and it works, however in our situation the UPS is doing all kind of funny things.... but it sends the 'power on battery' command to the NAS (and thus sends an email) all the time (4+ times a day), and almost immediatley send the 'power returned to normal' command/email. Im assuming probably its the AVR kicking in and I need to adjust the tolerances a little, as we live in the country it could actually be the AC power fluctuations causing this...

Anyway, all that aside, what lines should i comment out to stop the on batt, and power returned to normal emails being sent? I actually also want the 'NAS is back to normal' email to still be sent after a forced shutdown as thats a good indicator of a real power-cut!

Thanks

[quietsy]

To stop the on-batt and on-line emails, comment the following lines in red on /usr/syno/bin/synoups:

UPSSendMsg() {
St=`UPSStatusGet`
if [ "$St" = "OL" ]; then
echo "UPS is On-Line"
return
fi
if [ "$St" = "OB" ]; then
echo "UPS is On-Battery"
/usr/syno/bin/synomail UPSDown
SYSLOG "UPS on battery."
return
fi
}

case "$1" in
online)
/usr/syno/bin/synomail UPSUp
UPSRestart
;;
onbatt)
UPSSendMsg $1
;;

Thanks so much for the detailed instructions! Synology should put this in the next release of DSM.

New DSM 4.0-2219 (2012/04/17)
Most important is the fix for the Samba leak. For this topic:(from the change log)
3.Added a notification event when the DiskStation enters safe mode due to UPS low battery.

I did not test it yet. FW update is in progress ....

Henkg,

Where did you find those release notes?
Thanks

[henkg]

Where they always are:
http://www.synology.com/support/download.php?lang=enu
(select bays / type, first table row. Last column: notes: Release notes)

In notifications,
- 'UPS low battery reached' is added.
- No other new setting (something like 'DS now on battery')
Can't test it now.

And was your test successful?
Do we get a notification (e-mail) when the NAS runs on UPS? (power outage)
