[collectd] NetApp plugin giving NANs

[Mark Syms]

 Hi all,

 I've been trying to use the NetApp plugin to monitor a NetApp Fas2020 
 that I'm working with. Collectd is running on Debian, I've built a 
 modified package of version 4.10.1-1 using the NetApp SDK to allow 
 enabling the NetApp plugin. The NetApp is running version 7.2.6.1 of the 
 system software.

 rrdtool info for the cpu-system.rrd file gives the following (the other 
 RRDs are similar).

 Do I have something misconfigured or does this plugin just not work 
 with this NetApp? Any help to get this working would be appreciated.

 Thanks,

 Mark.
