I have deployed Rancher Monitoring on a Rancher Imported K8s Cluster. It installed kube-prometheus-stack using helm charts in the backend. Which installed Prometheus Server, Prometheus Operator along with other components.
Now I have a couple of singe node K3s clusters, which are constrained devices and I would like to add them as Scrape Targets to the Prometheus server in the K8s Cluster. I have installed node-exporter and kube-state-metrics using helm charts in the K3s Clusters. But unable to have them discovered by the Prometheus Server.
I have searched in the internet, looking for the configuration steps. But no luck. Can somebody help me please. This is a PoC requirement and is a timebound activity. So any quick help would be greatly appreciated…Thanks in advance
