The instructions I was adapting from were here:

http://www.apcupsd.org/manual/manual.html#implementation-details

I posted to their mailing list first, but they indicated that rsyslog
questions should be addressed elsewhere.  I first tried on the Linux
Mint forums and then here when I received no response there.

After feedback on this list I have revised my approach.  This appears to
be working:

# attempt to get apcupsd logging working properly
#
# new approach after discussion on mailing list
#
# cribbing approach from 20-ufw.conf
#
# Everything for apcupsd goes here
#
local0.info;local0.!notice             /var/log/apcupsd.data
& stop
local0.notice;local0.!warn            |/var/log/apcupsd.status
& stop
local0.warn                            /var/log/apcupsd.events
& stop
#
# If I understand this correctly should route selected entries
# to apcupsd.* files and remove them from further logging
# any unaddressed apcupsd logging should wind up in /var/log/syslog
#

Anything in the above appear to need correction?  Did I miss anything? 
Thanks again for the assistance.
