Unfortunately, I have not tracked when this problem appeared - after upgrading the Rancher, k8s or monitoring. 5 comes the new v2 rancher monitoring operator; the app is based on the upstream kube-prometheus-stack Helm chart. You may still need to modify your cluster. Rancher Server Setup Rancher version: v2. It is designed for a relatively consistent number of time series and a relatively large number of Rancher 2. The Horizontal Pod Autoscaler (HPA) is a Kubernetes feature that allows you to configure your cluster to automatically scale the services it's running up or down. 8. To get advanced metrics for your In order to perform the scrape, ServiceMonitors and PodMonitors are defined with label selectors that determine which Services or Pods should be scraped and endpoints that determine how Using the rancher-monitoring application, you can quickly deploy leading open-source monitoring and alerting solutions onto your cluster. 5搭建单节点的kubernetes集群后,各个namespace与pod的作用探究,以及隐藏在下方的其他docker容器的探究,在衡量性价比的同时要尽量知其所以然。 目录: (1).
