"SELECT SUM(rx_bytes) FROM..." will return the sum across all the series.
"SELECT SUM(rx_bytes) FROM...GROUP BY container_name" will return the SUM independently for each container_name It sounds like you are trying to sum up the total network traffic at each interval. Assuming the data is reported in 10 second intervals, a query like "SELECT SUM(rx_bytes) FROM...GROUP BY time(10s)" would return that. There is no way in InfluxDB to do a query like "SELECT rx_bytes + rx_bytes..." where one field is from the centos container, and the other is from the ubuntu box. You'll have to sum across intervals, not individually for every point.
