Pi as a UPS monitor
-
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

Say to yourself, WTF did I do 3 months ago....
Time to reload and start over.

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.
-
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): UPS jaredoffice@localhost on line power
-
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
-
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!
-
Now time to wipe, replicate, test and document.
Then the command can be changed to send email.

Following my own notes from post 62
At step 11 (installing nut form repo) I see an error.

So on to configuration. Nut has only a few config files you need to deal with.
We will go right down the list.
pi@bna-pwr-pi-01:~ $ ls -l /etc/nut total 44 -rw-r----- 1 root nut 1538 Mar 26 2015 nut.conf -rw-r----- 1 root nut 4572 Mar 26 2015 ups.conf -rw-r----- 1 root nut 4578 Mar 26 2015 upsd.conf -rw-r----- 1 root nut 2131 Mar 26 2015 upsd.users -rw-r----- 1 root nut 15170 Mar 26 2015 upsmon.conf -rw-r----- 1 root nut 3887 Mar 26 2015 upssched.conf
-
First up is
nut.conf
. There is only a single option to set in this file, but it is important.Assuming you are going to have only one device, or if multiple devices, that they will report in on their own, the simplest configuration is to choose
standalone
MODE=standalone
Here are the various meanings from the conf file.
# - none: NUT is not configured, or use the Integrated Power Management, or use # some external system to startup NUT components. So nothing is to be started. # - standalone: This mode address a local only configuration, with 1 UPS # protecting the local system. This implies to start the 3 NUT layers (driver, # upsd and upsmon) and the matching configuration files. This mode can also # address UPS redundancy. # - netserver: same as for the standalone configuration, but also need # some more network access controls (firewall, tcp-wrappers) and possibly a # specific LISTEN directive in upsd.conf. # Since this MODE is opened to the network, a special care should be applied # to security concerns. # - netclient: this mode only requires upsmon.
-
Next up is
ups.conf
, again read the config file for more information, it is fairly thorough.In this case I am going to connect it to the APC unit pictured at the beginning of this thread.
[bnajaredrouter] driver = usbhid-ups port = auto desc = "Jared Router UPS"
-
The file
upsd.conf
does not need modified for a typical standalone setup.
