This assumes that you use the Bash shell in your default environment.  It will 
need adaption if you use Dash.

In .bashrc define function getUPSstatus

  # Update variable UPSstatus and export to environment
  # Usage getUPSstatus <myups>
  function getUPSstatus {
    export UPSstatus="[$( upsc $1 ups.status 2>/dev/null )]:$( upsc $1
battery.charge 2>/dev/null )"
  }

The SHUTDOWNCMD declaration now simplifies to

  SHUTDOWNCMD "getUPSstatus <myups> ; logger -t upsmon.conf
\"UPS status is $UPSstatus\" ; /sbin/shutdown -h +0"

Thank you!  Sorry for another bonehead question…. Do I replace <myups>
with the IP address of the NUT Server/Synology?  I’m assuming I would use this
version for use in Dash with Ubuntu, correct?

Yes, you replace <myups> with the address of your UPS, for example 
"ups at 192.168.x.y".  Are you using Dash or Bash?  If it's Dash,
the function
getUPSstatus probably goes into .profile .

Test on the command line before modifying SHUTDOWNCMD by typing the commands

  getUPSstatus <myups>
  echo "UPS status is $UPSstatus"

You should see "UPS status is [OL]:100".
