 * First, exclude fields that are on the exclusion list and don't
 * have names that suggest they contain metrics. Also exclude
 * field names that are blank.
 *
 * Next, look for a field that is of real type and contains one
 * of the preferred names (in order of the preferred names).
 *
 * Next, look for a field that is of integer type and contains
