Interface JAlarmSeverity

  • public interface JAlarmSeverity
    Helper class for java to get the handle of `AlarmSeverity` which is fundamental to alarm service

    • Field Detail

      • Okay

        static final AlarmSeverity Okay
        Represents the normal operation of the alarm

      • Warning

        static final AlarmSeverity Warning
        Represents the warning state of an alarm for e.g. the alarm is raised during the observation night and it is expected that day staff responds to it the following morning. It can be safely assumed that operation and performance of the observation is not impacted by alarm raised with `Warning` severity.

      • Major

        static final AlarmSeverity Major
        Represents the major state of an alarm for e.g the operator needs to respond to a major alarm within 30 to 60 minutes. It can be safely assumed that major kind of alarms won't affect the observation operation but it may affect the performance of the same.

      • Indeterminate

        static final AlarmSeverity Indeterminate
        Represents the indeterminate state of an alarm, for e.g. hardware is not able to update the state regularly and hence component cannot determine the actual severity of the alarm.

      • Disconnected

        static final FullAlarmSeverity Disconnected
        Represents the disconnected state of an alarm. This severity is never set by a developer explicitly. Rather it is inferred as `Disconnected` when the severity of an alarm expires and component is unable to refresh the severity.

      • Critical

        static final AlarmSeverity Critical
        Represents the critical state of an alarm for e.g. the operator needs to respond to a critical alarm within 30 minutes. It can be safely assumed that operation cannot continue if a critical alarm is raised in the system.
