Cannot setup Universal Device Poller Custom Chart

Hi all.

Trying to setup a new (first time on this install) poller chart.

What i want to do is to group switches and nodes within a datacenter into a group, and then monitor these devices for temperatures and fan speed.

The idea being if we loose an aircon unit, we can see rising inlet temps as a change.

anyway - when i click the 'configure this resource' and i am taken to the modifiy page. On the Y axis i have 'select Universal Device Poller' - but on that drop down i have no options !

any ideas?

I have searched, but not come up trumps.

Thanks in advance.
