public interface Alert
extends Externalizable

An interface representing an alert issued by an alert bean or an alert provider.

An alert has a unique alert id (getAlertUid()) and is fired by one of the alert beans, and aggregated with other alerts of the same (getGroupUid()).

An unresolved alert is an alert that indicates a problematic situation that needs attention. An alert bean can trigger more than one unresolved alert if the problem persists (with the same alert group UID). A resolved alert (AlertStatus.RESOLVED) is an alert that indicates that the situation was resolved, or is no longer in need of attention.

Each alert has descriptive information of the alert (getDescription()), data and time of the alert (getTimestamp()), and configuration properties together with runtime properties the alert bean exposes (see getProperties()).

The source component for which the alert was triggered (see getComponentUid()) can be correlated to one of the components using the Admin.getGridComponentByUID(String) if this component has not yet been terminated.
