This article describes the use of Node-exporter, Prometheus, Grafana to monitor the cluster in a k8s cluster.Its implementation principle is somewhat similar to elk, EFK combination. The Node-exporter component collects the metrics monitoring data on the node and pushes the data to Prometheus, Prometheus is responsible for storing the data, and grafana the data to the user in a graphical form on the Web page. Before you begin, it is necessary to under
