Report writer fields and hardware status

Hi Guys,

We don't currently have NCM, so i'm trying to work out a way to create a NPM 10.4 report that allows me to see the count of physical switches in a logical switch stack.

I know I can get this data as the "Current Status of each Hardware Sensor" gives me the count of physical power supplies and the "Current Hardware Status" gives me the Hardware Model.

I'm sure i'm missing something blindingly obvious, but when I go into the Report Writer, I seem to be able to add in fields for "Hardware" or "Hardware Sensor Type" / "Hardware Sensor" but not both.

Is there some way to configure what fields you add in when your selecting them as they don't always appear to show and appear to be tied somehow to the report itself.

Cheers
