[Nut-upsuser] UPS reboots with APC UPS

Hello,

I have been using NUT for a short period of time and have some questions 
regarding the UPS reboot signal that I can't figure out. Have tried some 
googling and reading the DOCs but I am struggling to understand how some 
variables / things are supposed to work, so would appreciate any help 
with any of the following questions.

I am running NUT on standalone mode on a linux machine (lets call it 
M1), connected via USB to the APC UPS. There is another Windows computer 
connected on the UPS (refer to as M2), which when not used is suspended. 
The windows machine (M2) is not managed by NUT due to not finding a NUT 
windows client but that's a separate thing.

My use case. When power is off the UPS should run till battery charge 
gets to 30%, then the shutdowncmd will issue a suspend to M1. UPS should 
continue running till power is back or battery runs out, as such the UPS 
should never be restarted or shutdown by NUT as that would kill the 
suspending. The UPS even at 30% should last couple of hours with M1,M2 
suspended and power cuts at worst last 30min. Obviously I accept the 
fact that if the battery runs out it will greatly reduce the lifespan of 
the battery.

I have issued upsrw -s battery.charge.low=30 apc1400 and set SHUTDOWNCMD 
"/bin/systemctl suspend" to reflect the above, so when battery.charge 
reaches 30% or available battery runtime is 120sec the computer should 
suspend, which it has done multiple times.

I am trying to understand what controls/triggers the UPS reboot signal.
1. Have had the UPS reboot while on power and 100% battery when manually 
restarting M1 for updates taking down both M1 (during boot, so the 
signal was delayed?) & M2 (was running). Have tried to reproduce it 
while writing this with a manual reboot / suspend to no avail.
2. UPS takes ~30min to reach 40% battery with M1 running and M2 
suspended. After manually suspending M1 15min in a power cut (took place 
yesterday), after couple of minutes the UPS rebooted. When the power 
came back the UPS reported 57% battery charge, so it didn't even reach 
LB either from battery.charge.low and couldn't have been 
battery.runtime.low if I have understood the setting correctly. This has 
happened a total of 2 times iirc.

I can't figure out which settings cause the reboots. Would setting 
ups.timer.reboot to -1 stop it from happening regardless the cause of 
triggering a UPS reboot? Though I would prefer understanding what is the 
cause.

[Nut-upsuser] UPS reboots with APC UPS

NUT is designed to

  1. Power off the system attached to the UPS when some criteria is reached, eg.
status [LB]

  2. Some time later, in your case ups.delay.shutdown = 20 seconds, the UPS
shuts
down its power outlets.

  3. When wall power returns, the UPS turns on it's power outlets and this 
provokes the attached system to power up.

In your case, instead of powering off the attached system, you begin a 
suspend/hibernate, but continue to take power from the UPS.  But the 
ups.delay.shutdown will still have an effect, and the UPS will turn off it's
outlets.

I don't see clearly how you intend to operate, but you may need to
neutralize
the "delayed shutdown" order to the UPS.  However if you do this, I
don't see
how it will be possible to resume from suspend.

I suspect that you would be best served by a big UPS which will carry you 
through most power outages, and use NUT to shutdown (not suspend) on LB, when 
it's clear that wall power has gone for the day.  There is no automatic
suspend
in that scenario.

While that holds true for the 1st example-case I stated on the 2nd one 
it was certainly couple of minutes before the ups did it's click sound 
(thought it was reboot but as you corrected me it's cutting power to the 
plugs). That could have been a fluke though?>

After x minutes LB is reached and M1 is set to suspend while power is 
not cut of the plugs of the UPS unit at any point in time. UPS operates 
with minimal load on it (basically two monitors from M2 that are on 
standby). Power comes back, everything continues to be as is. The resume 
from suspend will be manual (i.e. click the power button). I am fine 
with this approach and should work just fine right?
There is also wake-on-lan that works on suspend but would require a 
raspberry-pi or something similar.>

> As I think more of it, with the information you provided, the NUT 
approach is better as it allows for unattended restart of the machines 
regardless of downtime (well unless it exceeds the battery life). 
Regrettably the fact that M2 is suspended when I don't use it, is 
incompatible with that approach and not using suspend on M2 would mean 
starting up everything on M2 at least once per day.

Do you know whether ups.delay.shutdown -1 or ups.timer.reboot -1 
neutralize it? Or I will have to trial & error?

Thank you for your help!
