I right in thinking, for my single server running NUT (in standalone mode)
with connected USB UPS:
- when battery.charge reaches battery.charge.low: ups.status triggers to "LB"
and upsmon sets an FSD in motion
- upsmon waits FINALDELAY 5 seconds, and calls my shutdown command (which
then in sequence does a clean shutdown of my VMs before calling the 'real'
shutdown command)
- my server then shuts down and powers off
Main question:
"ups.delay.shutdown" - at what point does this variable kick in? Is
ups.delay.shutdown the period in seconds after FSD that the UPS will
hard-shutdown, i.e. I need to ensure that my server can complete clean
shutdown in that duration?
Yes, you do need to give your server sufficient time.
My understanding is that the ups.delay.shutdown is overwritten by the offdelay
option in file ups.conf.
In the machine with which I type this, I have
rprice@titan ~ upsc Eaton ups.delay.shutdown
20
rprice@titan ~ grep offdelay /etc/nut/ups.conf
offdelay = 30
See https://rogerprice.org/NUT/ConfigExamples.A5.pdf chapter 2.5, and chapter
2.7 line 77.
