Network Transfer Speeds (in MB/s) using Prometheus & Grafana

I am trying to create a graph in Grafana to display the machine's network transfer speeds (in MB/s or similar) by using the following Prometheus query

rate(node_network_receive_bytes_total[1m]) * 8

However, this is giving me a very flat graph and the value seems to be in the wrong order of magnitude as well.

enter image description here

Prometheus is scraping the default node exporter to obtain the metrics including node_network_receive_bytes_total and node_network_transmit_bytes_total.

enter image description here

iftop is showing the download transfer speed to be about 10+ Mbps, which is much higher than 1 KBps calculated in the Grafana graph.

What should be the correct query to calculate the network transfer bandwidth in Prometheus/Grafana?

Edit: Node exporter is running inside a Docker container.

It can happen if you run node exporter in docker container. Just configure use container host system network

docker run --network host

or in compose add

network_mode: host
