Custom graph no rrd files

I am not getting rrd files generate for a custom graph:

bb client message:

bb machine1 'status machine2.grpwiseusr green Thur Oct 25 09:46:42 EDT 2007 grpwiseusr : 812'

hobbitserver.cfg

..... TEST2RRD="cpu=la,...,ncv,grpwiseusr=ncv"

NCV_grpwiseusr="*:GAUGE"

GRAPHS="la,ncv,...,grpwiseusr"

.....................

Should I at this point see rrd files ? I see them for the built in scripts.
