If you see the following error, it could be due to SELinux being enabled. After running through the steps in this quickstart, you will have: Set up and configured Node Exporter to collect Linux system metrics like CPU load and disk I/O. This guide will walk you through the node-exporter setup on a Kubernetes cluster and integrate Prometheus scrape config to scrape the node metrics. Furthermore it might be necessary to manage the local firewalld and open ports like. ApIf you want to know how the Kubernetes nodes perform or monitor system-level insights of kubernetes nodes, you need to set up a Prometheus node exporter on Kubernetes cluster. name: Make sure nodeexporter service is started and enabled systemd: name: nodeexporter state: started enabled: yes daemonreload: yes.
