I have updated this ZenPack for V3 and would much appreciate some testers, especially if you have experience with the original version.  The only things I have changed are to do with the presentation aspects for the new V3 interface - I haven't touched any of the back-end statistics, creation of rrd files or graphing.

I have found a couple of issues which I think exist with both the original version and this updated one:

1) Beware if you are testing and creating a new template that it takes about 2 days before there is enough
data for the Holt-Winters RRA archives to have data so although you see the new lines on the legend of a
graph, there are no data lines for this long.

2) I don't think installing the ZenPack per se, will corrupt anything you currently have; however it may cause
problems to existing data. Have a look at message/50360#50360 - I have seen this
both on the old version with 2.5.2 and with the new. I would take my own backup of RRD files before applying
a predictive threshold.

Please provide feedback.

Cheers,

Jane
