Alarm Code
An alarm code uniquely identifies an alarm.
Description
Alarm description summarizes the fault information, such as the fault cause and
phenomenon.
Severity
There are four alarm levels, which are indicated in descending order of severity as Critical,
Major, Minor, and Warning.
l
Critical
A critical alarm indicates a fault that causes failures of system operations or service
capabilities. Immediate troubleshooting is required when a critical alarm is reported.
l
Major
A major alarm indicates a fault that seriously impacts proper system operations or
reduces service capabilities. Clearing the fault to restore the system as soon as
possible is required when a major alarm occurs.
l
Minor
A minor alarm indicates a fault that slightly influences proper system operations or
reduces service capabilities. Proper measures should be taken to clear the fault in a
timely manner and prevent the occurrence of more severe alarms when a major alarm
occurs.
l
Warning
A warning indicates a fault that has a potential or gradual impact on proper system
operations or service capabilities. Warning messages need to be analyzed and proper
measures should be taken to clear the fault in a timely manner and avoid more severe
alarms.
The impact degree described in the definition of alarm severity refers to the impact on a
single index, for example, reliability or security. Once the impact on any index reaches the
specified threshold, the severity level of the alarm can be roughly determined. If an alarm
has an impact on multiple indices, its severity level should be escalated accordingly.
Alarm Types
Based on the triggering condition and system impact, alarms can be classified into the
following five types:
