I dont understant why status of my object is still MAJOR (see pictures). There are no alarms, StatusPoll looks ok, only think I see is 1 month old minor event, but it was repaired and now is ok. Maybe its Newbie question, but only way how to solve it for me is to delete events in SQL database or set EventLogRetentionTime to 1 or 0 to clean EventLog.
Please check that group everyone has System Right "View all alarm categories". Node status is not affected by events. It can be affected by status calculation(properties of object), by default status is calculated based on child object status, alarms, and DCI's that have "Use this DCI for node status calculation" option selected.
