Unfortunately, I can do this only when retrieving data, in a VDEF, not in a CDEF to be actually stored that way, right?
By the way, can I use VDEF in a export? from documentation it is not evident when VDEF are allowed. Finally, as this requirement comes frequently, will you eventually consider to incorporate TOTAL (or SUM) CDEF a feature of RRDTools?
