[Orca-users] Warning: cannot create '': fetching cdp from rra

[Diana N]

Apparently the problem was in the rrd files. I renamed
the two that had problems and Orca regenerate them and
the two missing graphs. 

Thanks for your help!!

Best regards,

     Diana.

PS: by the way, if I decide to install a new version
of rrdtool, will I have to recompile Orca? How does it
know it has to use the new version otherwise?
