Hello everyone, I'm new to Rancher and am evaluating how to implement it for managing Kubernetes clusters. I have a few questions and would appreciate your guidance: Viewing pod and node metrics: In the Rancher interface, I see basic node and cluster information, but I can't see detailed pod metrics (CPU, memory, disk usage, etc.). The clusters already have Prometheus and Grafana installed via Helm, but not from Rancher. Are there any additional steps required for Rancher to display these metrics? Namespace-level permissions: I've given a developer full namespace-level permissions, but they still can't see pod metrics in their namespace. Are any additional permissions or specific configurations required for them to view these metrics from Rancher? I welcome any guidance, configuration examples, or best practices for enabling pod monitoring by namespace in Rancher when using external Prometheus/Grafana.

Can you tell if you have metrics-server running in the cluster?

I have 3 clusters where the metric server is active, but where I have Rancher installed I don't have the metric-server.

Apologies, strike that. I stood up a central cluster where I run prometheus/grafana and it pulls in metrics from other clusters. I can tell you basically how I set that up. I'm not sure if that meets your use-case, though.
Here is something I found: Rancher’s built-in graphs only light up if Rancher Monitoring (Monitoring V2) is installed in that cluster.

This means that you must install the monitoring theme in the app on all clusters to activate the microservices metrics.
Good afternoon When installing the Rancher monitoring stack, I see that the basic metrics are already loaded in the Rancher admin console under the pods option. This means that SCTAK must be installed on all clusters and won't work if it's already installed elsewhere.
