Method Detail

getLatestEventByAlertDefinitionId

org.rhq.core.domain.alert.AlertDampeningEvent getLatestEventByAlertDefinitionId(int alertDefinitionId)

processEventType

org.rhq.core.domain.alert.Alert processEventType(int alertDefinitionId,
                                               org.rhq.core.domain.alert.AlertDampeningEvent.Type eventType)

Performs processing as needed for the type of event on the given AlertDefinition. If the condition set for an alert definition has been satisfied, and the chosen dampening rule has also been satisfied, it will fire an alert. In most instances, this can be calculated immediately and synchronously at the time this method is called. However, in at least one instance, this can not be known immediately. Thus, in this case, the method will start a timer to keep track of when it should fire an alert in the future. Subsequent calls to this method will either update or delete the timer as appropriate to satisfy the business semantics of the supported dampening rules.

Parameters:

alertDefinitionId -

eventType -

Returns:

the Alert fired as a result of the event satisfying the dampening rules for the alert definition, or null if no alert was fired.
