Cluster events provide information about the status of clusters, which enables you to monitor the clusters for potential problems. The events are grouped by impact area, and include the event name, trap name, impact level, source type, and severity.
Impact area: availability
An asterisk (*) identifies EMS events that have been converted to Unified Manager events.
