Manage real-time alarms
Perform this task to filter, ignore, view, confirm, or clear alarms generated most recently. Expired real-time alarms are moved to the history alarm list.
Restrictions and guidelines
By default, the system refreshes the alarm information page every 10 seconds. Configure an appropriate refresh interval to ensure that operators can confirm the alarms before the page is refreshed.
A container alarm threshold is rounded to two decimal places, and the alarm values displayed in the real-time alarm list are rounded to two decimal places. A displayed alarm value might be different from the actual alarm value, and the difference does not affect the accuracy of alarms.
