NUT notifications not working on pfsense+

dennypage

Have you successfully tested SMTP notifications in System / Advanced / Notifications?

Austin 0

@dennypage Yes the test emails went through fine. It also sent me the notification when it powered back on after the power outage.

@austin-0 Please post the contents of /usr/local/etc/nut/upsmon.conf.

And the sha sum of /usr/local/pkg/nut/nut_email.php:

@austin-0 It was the contents of /usr/local/etc/nut/upsmon.conf that I was looking for.

Your /usr/local/pkg/nut/nut_email.php is fine.

@dennypage Looks like I misread your request. Here is the config file.

@austin-0 Please try the following:

/usr/local/pkg/nut/nut_email.php test

Does this produce an email? Or an error?

Austin 0

@dennypage It sent me an email.

dennypage

@austin-0 Hmm... I see nothing currently wrong.

Is it possible that NUT wasn't actually running at the time of your event? Or that the email messages were suppressed by your mail handler? Or put into junk? Or some other form of automated disposal?

You said that you had done additional testing. What did you test?

About the only thing left to do is to test by disconnecting the UPS, or disconnecting mains. Be sure you are logged in (ssh) when you do it. When you disconnect, you should receive both a message in your terminal window and an email message. If you don't, check both the UPS status and the system log file for indications of error.

@dennypage After first installing NUT I did make sure it actually recognized the UPS. I tried testing the email notifications at that time by simply unplugging the UPS for a few seconds, and did note that they weren't working. It just kind of got put on the back burner though to be honest. There is a small chance that the nut service was running at the time, but I was accessing the firewall the night before, and the service was running then. I am running the mail through gmail, and it emails both to and from my personal email. I have checked through the "All Mail" folder to make sure it wasn't just in junk. However I do think that this is the first time that firewall has been restarted since I turned the notifications on for the NUT package. I suppose it is possible that rebooting it fixed the issue. I won't be test unplugging it again until Friday, as that is the next time I will have physical access. Does it need to hit a certain battery percentage to send the notification?

Initial notification that the UPS is on battery should be immediate.

FWIW, you can just disconnect the USB connection (assuming that is what you are using), and you should receive an immediate notification that the UPS is unavailable. On most UPSs you can also run a self test, which should also produce an "on battery" notification.

Call me old school, but I generally prefer pulling the USB connection, doing a self test, or even popping the breaker instead of pulling the mains cord. The reason for this is that pulling the mains cord also disconnects the ground.

May be a dump question: was it possible, that the outage disconnects the line to the mail server?
I am using NUT at my SG-3100 and as far as I remember I did not configure anything else than the SMTP settings.

The UPS is scheduled for a self-test every two weeks an I get an e-mail immediately when UPS is on battery.

@fsc830 Thank you. Yes I was talking to my co-worker, and I realized that I don't currently know what the ONT is plugged into. So it 100% possible that the ONT went offline, which would explain the lack of emails. Something else I will have to look into Friday when I go up there.

Austin 0

I have double checked and the ont was on a battery backup. I unplugged the USB cable and still there was no notification sent. I did verify that the UPS status in nut changed. It just did not send a notification. I found a interesting message in the log though. ups_status_set: seems that UPS [OfficeUPS] is in OL+DISCHRG state now. Is it calibrating or do you perhaps want to set 'onlinedischarge' option? Some UPS models (e.g. CyberPower UT series) emit OL+DISCHRG when offline.

This is puzzling.

Were you logged in on the console (ssh) when you disconnected the USB cable? Was there a notice there?

Austin 0

@dennypage I just tested it, and yes it does give a notification in the ssh connection.

That's good--it means NUT itself is working.

Still very puzzling. I'd like to verify the contents of the pfSense NUT package. Can you please execute the following:

ls -l `pkg info --list-files pfSense-pkg-nut`

and

sha1sum `pkg info --list-files pfSense-pkg-nut`

[don't worry about the no such file or directory error for pfSense-pkg-nut-2.8.0_2]

@austin-0 That is all correct. I'm not seeing anything wrong from a NUT pov.

Let's try the notification again and check the system log to see if there is any indication of the issue. Run this:

php-cgi /usr/local/pkg/nut/nut_email.php this is a test

followed by this:

tail /var/log/system.log

There should be a line in the system log for the php-cgi command referring to notify_monitor. What does it say?

dennypage

@austin-0 While we're at it, we might as well just do this:

grep notify_monitor /var/log/system.log

This will include the prior attempts as well.
