NCV variable for custom RRD's

Hello all,

I recently added a custom test to our hobbit setup that will use the NCV format for the rrd graph. The only problem that i noticed is the option to use wildcards in the NCV_test variable to define the "default" dataset type. When i specify all the datasets in the environment variable and set them to GAUGE (wich i need for my test), it all works fine, but if i use the "*:GAUGE" in this variable the rrd is generated with datasets of the "DERIVE" type. Anyone a idea what can be wrong?

Kind regards, Ivan
