[hobbit] Problem with hobbitd_rrd custom graph

[Davíð Steinn Geirsson]

Hi Henrik,

Thanks for this, my values were defined as GAUGE but the problem was 
fixed by the patch submitted by Graham Nayler. This hobbit install is 
running a 4.3 snapshot from late 2007.

See this mail for the referenced fix: 
http://www.hswn.dk/hobbiton/2008/09/msg00283.html

After applying, I can confirm that values are coming into the database 
at every run so far.

Now to finish the graph definition. :)

Kind regards,
Davíð
