 [NOTE]
 ====
 
-- BYOC and Dedicated clusters can export Redpanda metrics to a third-party monitoring system. Serverless clusters _cannot_ export Redpanda metrics.
 - To maximize performance, Redpanda exports some metrics only when the underlying feature is in use. For example, a metric for consumer groups, xref:reference:public-metrics-reference.adoc#redpanda_kafka_consumer_group_committed_offset[`redpanda_kafka_consumer_group_committed_offset`], is only exported when groups are registered.
 - Operating system-level and node-level metrics (such as CPU, memory, disk, and network usage) are not available through this endpoint. For infrastructure monitoring, use your cloud provider's native monitoring tools (such as Azure Monitor, AWS CloudWatch, or Google Cloud Monitoring).

+Use xref:reference:rpk/rpk-generate/rpk-generate-grafana-dashboard.adoc[`rpk generate grafana-dashboard`] to generate a sample dashboard from the examples repository that you can import into a Grafana instance.
