Kpi data traffic

Is the kpi data traffic counted in the datapoint traffic of DataMailbox?

Are you asking about the number of datapoints or the VPN traffic?

if i use a kpi i produce traffic on the number of datapoints, on the VPN traffic counter, or the kpi don’t produce any traffic ?

It would produce traffic if you are viewing the KPIs over the VPN connection or through M2Web, but only while you are viewing them.
