[Nut-upsuser] Shutdown script does not trigger

[Rémi Lavergne]

Dear nut users,

I am fighting to configure a smooth server shutdown with an ubuntu 
server and a dell usb ups using nut.

It seems that the drivers connect properly (upsc gives very coherent 
outputs).

However I can't get anything to happen when the ups goes on battery.

How can I be sure the the UPS status is really monitored ?
Is there a particular log file where I upsmon reports problems ?

This is how it looks right now :

root at srv# ps -elf | grep -e upsd -e upsmon -e usbhid-ups
1 S nut       1152     1  0  80   0 -  4202 poll_s 14:27 ?        
00:00:03 /lib/nut/usbhid-ups -a dell
1 S nut       1154     1  0  80   0 -  3641 poll_s 14:27 ?        
00:00:00 /sbin/upsd
1 S root      1156     1  0  80   0 -  3632 pipe_w 14:27 ?        
00:00:00 /sbin/upsmon
5 S nut       1158  1156  0  80   0 -  3632 hrtime 14:27 ?        
00:00:00 /sbin/upsmon
1 S root      1381     1  0  80   0 -  3632 pipe_w 14:34 ?        
00:00:00 upsmon
5 S nut       1383  1381  0  80   0 -  3632 hrtime 14:34 ?        
00:00:00 upsmon

My nut configuration is :

     driver = usbhid-ups
     port   = auto

to be executed...)

# the timers, here 30 sec after the ONBATT (ups on battery) event

I'm quite new to nut so don't hesitate to tell me if these settings 
don't make sens !

Thanks in advance,

Rémi.
