Viewing Grafana Dashboards is throwing an error

[juergenfl]

Hi all, I have deployed the OpenTelemetry Demo App to a K8s cluster into a dedicated namespace and I'm facing issues with the Grafana configuration.

Grafana is throwing a server lookup error: prometheus-server: no such host

When looking at the services, I can confirm that this is correct the service is only named "prometheus", not "prometheus-server":

Could this be caused by my dedicated namespace "otel-demo-app" ???

I got the issue resolved, looks like it got triggered by using a recent version of kubectl (v1.32.2) on my Mac. When deploying it from a Linux VM with kubectl version v1.31.2, all is good now:

$ kubectl get pods -n otel-demo-app
NAME                                               READY   STATUS    RESTARTS   AGE
