Interface Alarm

public interface Alarm

Alarm Constants. An alarm can be of two types: Stateless, when the producing MBean keeps no state about the occurence of the alarm. The produced alarm notification must have alarmState STATE_NONE and the valid severities are SEVERITY_NORMAL -> SEVERITY_UNKNOWN Stateful, when the producing MBean keeps state about the occurence of the alarm. The first notification must carry alarmState STATE_CREATED, with valid severities SEVERITY_WARNING -> SEVERITY_UNKNOWN. Any change in the alarm (severity) must generate an alarm notification with alarmState STATE_CHANGED and valid severities SEVERITY_WARNING -> SEVERITY_UNKNOWN. The clearance of the alarm must be indicates with an alarm notification with alarmState STATE_CLEARED and a severity of SEVERITY_NORMAL. This complexity is required in order to be able to easily correlate alarms and associaty the generation and clearence of system faults.
