Handling Container Alarms¶
HSS displays alarm and event statistics and their summary all on one page. You can have a quick overview of alarms, including the numbers of containers with alarms, handled alarms, and unhandled alarms.
The Events page displays the alarms generated in the last 30 days.
The status of a handled alarm changes from Unhandled to Handled.
