Hi,
I am trying out node-exporter in Docker, and I would like to acquire the node_network_receive_bytes_total of my host machine (This is simply a statistics which is used for measuring how much data are flowing into the machine). Right now, node_network_receive_bytes_total is possibly referring to the virtual eth0 of the containerized node-exporter and not the actual host machine itself. I have tried wget on the host, and node_network_receive_bytes_total does not move at all. But when I tried wget in the containerized node-exporter, node_network_receive_bytes_total increases with respect to the amount of incoming bytes.
node_network_receive_bytes_total refers to the value from /proc/net/dev (src: https://github.com/prometheus/node_exporter/issues/1849 )
Right now, for convenient-sake, I am using Docker-Compose which contains Prometheus, Grafana, Node-Exporter, etc. and deploy everything in one go. In this case, is it possible to instruct node-exporter to refer to the host machine’s /proc/net/dev? Or make it so node-exporter is deployed on the host and not in the container while still using Docker-compose?
Thank you
