Check this awesome 'howtograph' that Henrik just posted on his website

That might explain lot of your rrd issues.

Hello,
I've been adjusting the BB informix script to send informix info to hobbit, that works flawlessly. Next part is creating a graph with the usage of the DB Spaces to monitor evolution. In a first instance I want to avoid having trouble with a dynamic number of DB Spaces and I tried to create a graph that's pretty static and limited to two DB Spaces. Creating the RRD and so all seems to go fine but when I look at the graph, in the legend it stays constantly at zero, it simply does not display the DBS usage number and it draws a line on the bottom of the X-axis.
version: hobbit-4.0.2 (yes I know, I still need to upgrade, maybe this is the issue itself?)
informix.sh creates the following output: DS:dbsusage1:DERIVE:600:0:100 DS:dbsusage2:DERIVE:600:0:100 informix.rrd 44:66

I don't really see any error in the RRD file, nor in the output of my script or hobbitgraph.cfg. Ofcourse informix is added to hobbitlaunch.cfg in the extra tests and extra script parameters. Logs don't display anything weird neither.
Perhaps someone can help me with finding my error. Thanks in advance.
