  Alarm:

o  An alarm refers to the notification reported when a fault is detected by the system.

o  A fault refers to a physical or logical factor, such as excessively high CPU usage,

hardware fault, or network cable disconnection, which causes a system failure.

o  Both generation time and clear time can be obtained.

  Alarm Severity

  Critical

If a critical alarm is generated, devices or resources may not work at all. Emergent

recovery is required.

  Major

If a major alarm is generated, the service quality of devices or resources has been

seriously deteriorated. Quick measures are required.

  Minor

If a minor alarm is generated, the service quality of devices or resources has been

slightly deteriorated. Proper handling or further observation is required in case that a

serious fault occurs.

  Warning

If a warning alarm is generated, the service quality of devices or resources is potentially

affected. Different measures are taken for different errors.
