Custom graphs: RRD database won't populate

[Haertig, David F (Dave)]

I'm trying to do my first custom graph, using data collected from a
custom script.
 
The script collects data fine, and successfully updates hobbit at it's
regular five minute increments.  The data as sent looks like this:
 
five : 17
ten : 24
fifteen : 30
twenty : 42
thirty : 62
fortyfive : 81
sixty : 108
ninety : 166
onetwenty : 218
oneeighty : 349
The column name is 'recent'.  Here's BBHOSTS:
group-only recent|pending|stuck Maestro
0.0.0.0 maestro_alarm_cases # prefer noconn recent pending stuck
NAME:"Alarm Cases"

and hobbitserver.cfg:
TEST2RRD="cpu=la,disk,inode,qtree,memory,<more
stuff>,ports,clock,lines,recent=ncv"
NCV_recent="five:GAUGE,ten:GAUGE,fifteen:GAUGE,twenty:GAUGE,thirty:GAUGE
,fortyfive:GAUGE,sixty:GAUGE,ninety:GAUGE,onetwenty:GAUGE,oneeighty:GAUG
E"

I stopped/started hobbit server.  I've been watching the 'recent' column
update regularly every five minutes, for at least 45 minutes now.
But there doesn't appear to be any RRD data file for this 'recent' test:
find /development/hobbit/data/rrd -name "*recent*" -print
The above 'find' command finds nothing related to 'recent' (although
there are plenty of OTHER test's RRD files in that directory - default
tests - just not my custom test)
I must have missed something simple.  I've gone over the hobbit
webserver's HTML help on "Custom Graphs" several times, but can't find
the cause of my error.
