help with NCV

[Gatis A.]

Hi,

Could you help me with configuring NCV please.
I want to graph "USERS ACTIVE".

If there is a plain

"USERS ACTIVE: x"

Then graph is made fine, but if there is something more I get:

2008-11-04 14:04:30 RRD error updating
/home/hob/hob/data/rrd/host1/rbackup.rrd from 127.0.0.1: tmplt contains more
DS definitions than RRD

How can I tell NCV to ignore everything beyond "USERS ACTIVE" line?

This is my output:

USERS ACTIVE: 6
