 For default platform monitoring, you add cluster ID labels for metrics in the `write_relabel` settings for remote write storage in the `cluster-monitoring-config` config map in the `openshift-monitoring` namespace.
 
 For user workload monitoring, you edit the settings in the `user-workload-monitoring-config` config map in the `openshift-user-workload-monitoring` namespace.

+[NOTE]
+====
+When Prometheus scrapes user workload targets that expose a `namespace` label, the system stores this label as `exported_namespace`. 
+This behavior ensures that the final namespace label value is equal to the namespace of the target pod.
+You cannot override this default configuration by setting the value of the `honorLabels` field to `true` for `PodMonitor` or `ServiceMonitor` objects.
