Hi,

Which algorithm is used by group-aggregate to down sample metrics.

Largest Triangle Three Bucket (LTTB), or average value etc...

Thanks

It depends on query. It can be average, sum, min, max, or count. The function is one of the parameters of the group aggregate query. The default is average.
