This creates a ServiceAccount, ClusterRole, and ClusterRoleBinding for the GrafanaAgent resource. It also creates a GrafanaAgent resource and specifies an Agent image version. Finally, the GrafanaAgent resource specifies `MetricsInstance` and `LogsInstance` selectors. These search for MetricsInstances and LogsInstances in the same namespace with labels matching `agent: grafana-agent-metrics` and `agent: grafana-agent-logs`, respectively. It also sets a `cluster: cloud` label for all metrics shipped your Prometheus-compatible endpoint. You should change this label to your desired cluster name.

Finally, the GrafanaAgent resource specifies `MetricsInstance` and `LogsInstance` selectors. These search for MetricsInstances and LogsInstances in the **same namespace** with labels matching `agent: grafana-agent-metrics` and `agent: grafana-agent-logs`, respectively. It also sets a `cluster: cloud` label for all metrics shipped your Prometheus-compatible endpoint. You should change this label to your desired cluster name. To search for MetricsInstances or LogsInstances in a *different* namespace, please use the `instanceNamespaceSelector` field. To learn more about this field, please consult the `GrafanaAgent` [CRD specification](https://github.com/grafana/agent/blob/main/production/operator/crds/monitoring.grafana.com_grafanaagents.yaml#L3789).

The full hierarchy of custom resources is as follows:
