Grafana Influx db net traffic way to high

So i collect my net data per telegraf and visualize via grafana. seem to work good but today i copied some files from my pc to my Unreid nas. and i see that in my graph the bandwith goes up to over 600MB/s. and thats not possible by a one gigabit ethernet. it should be arround 10mb/s.

I looked then into influxdb database and there are the values way to high too. so have i missed a setting? is telegraf collecting wrong data ?

Is it a simple discrepancy between bits and bytes?
