These don't match. I guess your Hobbit created the rrd file using the
default DERIVE datatype, before you remembered to put in the NCV_usage
setting. That's why your graph stays at 0 - DERIVE tracks changes,
whereas GAUGE tracks absolute values.

Make sure that hobbitd_rrd has been restarted after you changed the
NCV_usage setting. Then delete the rrd file; the next time Hobbit
creates it it should have the correct dataset type, and your graph
should start showing the values you expect.
