em_unique_nodes shows type Unknown for CIs on domain separated instanceIssue On a domain separated instance, the em_unique_nodes table has many entries with type Unknown, even though the related nodes exist on the CI table. Release All Cause By default, em_unique_nodes entries are calculated based on em_event. If the system property evt_mgmt.use_alerts_cis_in_license, true has been added, the entries are calculated based on em_alert instead. If the CI and the em_event (or em_alert) are in different domains, the CI is marked as type: Unknown on the em_unique_nodes table. Resolution Keep em_event and em_alert in the same domain as the related CI.
