Some of those hosts haven't NUT including upsmon (and other software

I think shutdown them via ssh would be enough and creating some
replacement for upsmon is too much.
Perhaps it is possible to have a micro upsmon in the form of a cron job in
every slave which, every minute, runs something like
rprice@maria:~> X=$( echo "GET VAR my-ups battery.charge" | netcat -w1
upsd-server 3493 )
rprice@maria:~> if [[ "$X" =~ \"([0-9]*)\" ]] ; then Y=${BASH_REMATCH[1]};
else Y=999 ; fi
rprice@maria:~> if [[ "$Y" -gt 35 ]] ; then echo "Carry on $Y" ; else echo
"Shutdown $Y" ; fi
Carry on 100
Different slaves could have different low battery values. I'm sure that a
netcat expert would be able to find a way of executing netcat only once.
