When storing metrics for multiple retention intervals, you must configure how to aggregate the data.
For example, you can sum the values, or you can calculate the average (and also standard deviation), or min, or max, or ... -- and, often, you want all of those for the coarser bucket.
However, I can find no way to configure what aggregation function is used for the coarser databases. Is it summing, or averaging, or something else?
Is there any documentation on this at all? I can't find any on the Wiki.
