I see the following three confimaps are removed from recently change:
grafana-dashboard-nodes, grafana-dashboard-pods, grafana-dashboard-statefulset

# oc get cm -n openshift-monitoring 
NAME                                        DATA      AGE
cluster-monitoring-config                   1         34m
grafana-dashboard-k8s-cluster-rsrc-use      1         33m
grafana-dashboard-k8s-node-rsrc-use         1         33m
grafana-dashboard-k8s-resources-cluster     1         33m
grafana-dashboard-k8s-resources-namespace   1         33m
grafana-dashboard-k8s-resources-pod         1         33m
grafana-dashboards                          1         33m
prometheus-k8s-rulefiles-0                  1         33m

If the change is expected, then there will not be "Nodes", "Pods" and "StatefulSets" page in grafana UI. Then this defect could be closed as NOTABUG

Yes that was intentional, as those dashboards are of poor quality and had a lot of duplicate information with the remaining dashboards. We prefer just shipping the high quality dashboards instead and will extend them in future releases with information currently not available.
