Service Alarms
Purpose
The key piece of functionality in the Service Supervision is identifying which services are impacted by traffic affecting equipment alarms. This feature is useful when troubleshooting a service problem.
The Alarm List dialog filters the alarms based on the selected element(s), e.g. list only the service alarm of the selected service(s) or list all the alarms of the service(s), service path(s) and service components.
Please note:
Important points about service alarms:
• Only one service alarm is active per service.
• If a service alarm changes severity, the active alarm is cleared and a new alarm is raised.
• Only traffic affecting equipment alarms are monitored for service alarms.
• Only Major and Critical Alarms are monitored for the service alarms.
Service Alarm Severity
− The mapping of equipment alarms to service fault state is configurable via /opt/nem/etc/singlePathServiceAlarmMapping.cfg and /opt/nem/etc/multiPathServiceAlarmMapping.cfg
− A default configuration is pre-installed, the values are shown below:
