Hi @hnhai
Is there any other pod running on the nodes which could be occupying port 9100 ?

@Thakurvaibhav I don't have permission to check it. Can I change port of node-exporter ?
If change how can I config prometheus to pull metrics from node-exporter. Tks !!!

@hnhai Node exporter uses hostNetwork: true, imo changing the port would not be a great idea. I would suggest looking for applications which are occupying port 9100 on the host.
