When trying to add a cluster data source into Unified Manager (UM) an error appears on the UI:
Unable to add cluster data source. This can occur if the clocks on the systems are not synchronized and the Unified Manager HTTPS certificate start date is later than the date on the cluster, or if the cluster has reached the maximum number of EMS notification destinations.
