No version of this template has had RRD support for the power test (yet). If 
you have a temperature sensor, the 'temp' test should though.

This should not be necessary in 4.2.3 or later.

The devmon collector is intended for devmon's TABLE:rrd operator in message 
files, however the power test doesn't operate on any repeater OIDs. The ncv 
module may be more appropriate, but it may choke on some of the non-numeric 
values that follow colons in the message file ...

Please supply the output of:
bb localhost 'hobbitdlog ups.power'

or equivalent, where 'ups' is the host name of your APC 9619 in the bb-hosts 
file.

The 'rrdtool info /path/to/file.rrd' would also help shed some light here.
