Could you also grep for upsd and upsmon in the NAS log?  Is this possible?

So proton is a slave, and is being made to shut down.

The variable USPstatus set by getUPSstatus was not in the environment for the 
echo command.  To get this to work, you'll have to put the upsc commands 
directly in SHUTDOWNCMD, or create a short script and call the script in

Could you tell us your topology?  Which system is master and which is slave? 
Do you have multiple slaves?  The decision to shutdown is taken by the master, 
not the slave.

Is it possible to run script http://rogerprice.org/NUT/nut-report on the NAS? 
Could you run the script on one of the slaves and post the result here?
