Class AlertEvent

java.lang.Object
org.acemq.rabbitmq.admin.alerts.AlertEvent
public final class AlertEvent extends Object
A rule that breached, and the measurement that breached it.

One per label combination, so a rule about queue depth produces one of these per deep queue rather than one for the broker. That is the difference between "something is backing up" and "orders.new is backing up", and it is the whole reason the detailed metrics endpoint is worth its cost.
