After event handlers start generating events, view events and event details in Event Manager > Event Monitor. All Events shows events in a tabular format. Calendar View shows events by month or week in a calendar or bar chart format.
When rebuilding the SQL database, you might not see a complete list of historical events. However, you can always see events in real-time logs. You can view the status of the SQL rebuild by checking the Rebuilding DB status in the Notification Center.
