what interval did you configure for the NetApp plugin? There used to be 
a bug that caused this kind of behavior if the global interval was 
different from the interval used by the netapp plugin. If this error 
condition fits your setup, you might want to update to version 4.10.2. 
After this you have to delete all empty rrd files of the netapp plugin, 
as they have been created with with the wrong interval setting.

If updating is not an option for whatever reason you can adjust the
interval of the netapp plugin to your global interval, which should fix
the problem immediately. Or, if you know a lot more about rrd than I do,
you could edit the already created rrd files and adjust their update
interval, but I have no idea how to do that. But someone else on this 
mailing list might be able to answer this question.
