Class AlertEvaluationService

java.lang.Object

com.nmontytskyi.monitoring.server.alert.AlertEvaluationService

@Service
public class AlertEvaluationService
extends Object

Core alerting service that evaluates all enabled alert rules against the latest metric data for a given service.

Called after every metric record is persisted. For each rule the service aggregates the relevant metric over the configured evaluation window (default: 60 minutes) and compares the result against the rule's threshold using the declared comparator. When a rule is breached and the per-rule cooldown has expired:

1. An AlertEventEntity is persisted.
2. The cooldown timer for that rule is reset via AlertCooldownManager.
3. Email notification is dispatched via AlertNotificationService.
