the data type that the metric is represented internally (uint16 = unsigned
integer of 16 bits, so from 0 to 65535).
the important issues to consider are :
* if it is a numeric value with decimals use float or double with the best
fitting width based on precision as per IEEE_754
* if it is a numeric value without decimals use the best fitting width and
signed type.
int8 = -128 to 127
uint8 = 0 to 255
* if it is some text value use string.
both numeric values will be graphed over time, while the string values will
only show the last value through the frontend.
