Okay, nevermind, I just answered my own question.  The answer is, "yes, it
works the same for data as it does with status".

It helps if I don't have any typos in the configuration files! ;-)


The man page for the hobbitd_rrd program says that it "receives "status" and
> "data" messages from hobbitd via stdin, and updates the RRD databases used
> to generate trend-graphs".

> "The "ncv" module will automatically detect all occurrences of a "NAME :
> value" or "NAME = value" string in a *status* message, and generate an RRD
> file holding all of the name/value data found in the message" (my emphasis
> added).
