Is support for Prometheus/Grafana available only with a valid Rancher support subscription?

Resolution

Correct. To be more accurate, Rancher Support is only for the Prometheus/Grafana components that are natively embedded in Rancher 2.x for the functionality of monitoring and dashboards.

In the exceptional scenario of any legacy support subscriptions that are limited to RKE-only (without Rancher 2.x), it does not include support of Prometheus/Grafana that are set up externally to monitor the RKE clusters.
