The items option name "Do not keep History" is confusing and should be more clear.

I tried to collect serial numbers of devices. Since I don't care about the historical serial numbers of a device, they usually don't change, I set the "History storage period" to "Do not keep History". This says "do not keep historical values" but it means "values are not stored at all". Of course I am interested in the last collected value. Since I never got any values for these items it needed some debugging and help of the forum to solve this issue.

The settings name "History storage period" and the word history is about the past, thus all the values collected in the past, and it doesn't say anything about the actual (last) value.

This option should be renamed to "Do not store values".

(Further it would be a nice feature to add an option "keep last value only".)
