The Fault and Alarm component Web service records information about reoccurring faults and notifies the administrator with alarms. The alarms can be either JMX notifications or common base events.
When encountering error conditions, Web service implementations generate fault information and potentially emit alarms for severe error conditions. They emit fault and alarm information as common base events, using CEI and JMX management notifications. The common base event is an extensible XML schema for describing event information.
CEI is used as the infrastructure for notifying interested parties of events, and it provides a persistent event repository that supports flexible event queries based on XPath. This component also includes an MBean that generates JMX notifications directly. The use of CEI enables integration with other WebSphere® products, such as Tivoli® security products.
