An alert delay is a property of a rule set in SMARTView. The alert delay is the amount of time that must expire before the alert is displayed in the BES Dashboard. This provides sufficient time for a condition to be corrected by a restoring event or by timeout.
A delayed alert is sent to AlertServer and is defined as dormant. A dormant alert is automatically passed to the Business Enterprise Server database and Business Enterprise Server Reporting but is not displayed in the Business Service Dashboard. If the alert is not actioned by close alert processing or a timeout, a new event is created that updates the alert as active and adds a note to the alert indicating it is active and its True Time is adjusted. The new event is passed to the Business Enterprise Server database and Business Enterprise Server Reporting to update the alert accordingly and the alert is displayed in the Business Service Dashboard. Reoccurrences are accrued against a dormant alert and affect when the alert becomes active; that is, when the same alert reoccurs within the delay period, the delay period is restarted.
The alert delay feature is configured in SMARTView when building or editing rules. Whilst working with a rule, the alert delay can be set in the 'Rule Summary' tab. The alert delay can be configured in hours (hh) minutes (mm) and seconds (ss).
When an alert comes into BES and hits the rule with the alert delay, the alert will be hidden from view in the dashboard. The alert will remain hidden until it has been active for a greater time than the delay is defined for.
