Pi as a UPS monitor

gjacobse

Well - while I don't have a Pi yet, I do happen to have a LM 17.x system running as my Pandora Music box (Pithos). It's within reach of one of the several UPS units I have (I have like nine) so I used your process and got one set up:

Today will be tinkering with notification options.

Just got this:

Init SSL without certificate database
Error: Data stale

gjacobse

Went back through the commands above to validation / confirmation:

$ sudo nano /etc/nut/nut.conf

no changes - the same.

$ sudo nano /etc/nut/ups.conf

no changes - the same

 $ sudo upsdrvctl start
Network UPS Tools - UPS driver controller 2.7.1
Network UPS Tools - Generic HID driver 0.38 (2.7.1)
USB communication driver 0.32
Duplicate driver instance detected! Terminating other driver!

Okay - seems 'ok'

$ sudo upsd

curious.

@gjacobse I do not get that. Mine has been untouched since last night.

This is what I will be following to configure reporting/alerting.

@JaredBusch
Well push comes to Meh -okay. I restarted the box and it's polls now.

Won't do anything else with it for a spell to see if it retains it. It's been four days since I restarted it. Now - to reconnect to it as I had to pull the monitor off. X2Go works great,.. but only once I've signed in at the local. sure that is omething that can be changed.

Since reboot, the monitor has been running all the time. So it may have been simply that.

As for having multiple UPS monitoring, I was curious what you thought about having a central display which showed the status of each UPS monitored. That way you have one display to glance at for a health check.

Maybe something similar to the UBNT controller software - central configuration ability.....

Take the output of upsc and throw it up on a web page. Unless you want a local display, in which case it's actually more difficult.

AMQP / MQTT may be awesome for this at the transport layer. MQTT is an interesting protocol that let you define a "last will and testament" action in case something goes south.

Ansible/Puppet etc. can handle the central configuration.

Hey 3 months later.....

Alright, I plugged the thing back in and got to testing.

Yeah! It still communicates.

Pulled the power cord from the wall. UPS beeps, but nothing from nut.

Ok back to the manual and checking the conf files.

Well it would probably help if I told the thing what to monitor..
/etc/nut/upsmon.conf

MONITOR jaredoffice@localhost 1 upsmon demo master

Oh but those details have to match /etc/nut/ups.conf and /etc/nut/upsd.users. Well I already know that my unit is called jaredoffice@localhost from ups.conf. So just edit upsd.users.

pi@raspberrypi:~ $ sudo nano /etc/nut/upsd.users
# put at end of file
[upsmon]
password = demo
upsmon master

Now reload the monitor

pi@raspberrypi:~ $ sudo upsmon -c reload
Network UPS Tools upsmon 2.7.2
pi@raspberrypi:~ $

Then unplug the UPS. and get nothing.

look in the logs..
tail/var/log/syslog

think i got the same thing, and decide the same course of action, to which I have not moved forward with. Albeit, it's not on a rPi but a desktop - premise is the same.

Think we may have to create a user for the NUT system.... but again,.. can't work with it right now.

JaredBusch

Quick check of upsmon.conf found this, uncommented it.

# RUN_AS_USER nut

Rebooted Pi, unplugged UPS.

Broadcast message from nut@raspberrypi (somewhere) (Wed Feb  1 17:19:04 2017):

UPS jaredoffice@localhost on battery


Broadcast message from nut@raspberrypi (somewhere) (Wed Feb  1 17:19:24 2017):

JaredBusch

Syslog had this though.

Feb  1 17:19:04 raspberrypi upsmon[734]: UPS jaredoffice@localhost on battery
Feb  1 17:19:11 raspberrypi upssched[792]: Failed to connect to parent and failed to create parent: No such file or directory
Feb  1 17:19:24 raspberrypi upsmon[734]: UPS jaredoffice@localhost on line power

Back to the config files we go!
/etc/nut/upssched.conf

# PIPEFN <filename>
# This is commented out by default to make you visit this file and think
# about how your system works before potentially opening a hole.

FFS, but it gets better! Right below that, also commented out.

# LOCKFN <filename>
#
# REQUIRED.  This was added after version 1.2.1.
#
# upssched needs to be able to create this filename in order to avoid
# a race condition when two events are dispatched from upsmon at nearly
# the same time.  This file will only exist briefly.  It must not be
# created by any other process.
#
# You should put this in the same directory as PIPEFN.
#

So I update the config and make a directory forgetting to chown it from root /sigh...

PIPEFN /etc/nut/upssched/upssched.pipe
LOCKFN /etc/nut/upssched/upssched.lock

JaredBusch

Once it was all chowned...

Feb  1 17:33:08 raspberrypi upssched[793]: Timer daemon started
Feb  1 17:33:09 raspberrypi upssched[793]: New timer: onbattwarn (30 seconds)
Feb  1 17:33:39 raspberrypi upssched[793]: Event: onbattwarn
Feb  1 17:33:54 raspberrypi upssched[793]: Timer queue empty, exiting

And output to the screen:

Broadcast message from nut@raspberrypi (somewhere) (Wed Feb  1 17:33:39 2017):

The UPS is currently running on battery power!

JaredBusch

Now time to wipe, replicate, test and document.

Then the command can be changed to send email.
