Are you running node_exporter in Docker?

yes

What did you do that produced an error?

localhost:9100/metrics doesn't include "enp1s0":

TYPE node_network_transmit_bytes_total counter

node_network_transmit_bytes_total{device="eth0"} 0
node_network_transmit_bytes_total{device="eth1"} 3.502584e+06
node_network_transmit_bytes_total{device="lo"} 0

What did you expect to see?

node_network_transmit_bytes_total{device="enp1s0"}83.502584e+06

What did you see instead?

node_network_transmit_bytes_total{device="eth0"} 0
node_network_transmit_bytes_total{device="eth1"} 3.502584e+06
node_network_transmit_bytes_total{device="lo"} 0

I assume you're runnig it in a container without hostnetworking which is needed to capture the host network interfaces: https://github.com/prometheus/node_exporter?tab=readme-ov-file#docker
