Prime Home events are
divided into two main categories: Application Traps and Network (CPE related)
Traps. In each category there are two sub-categories: Threshold Alarms and
Event Alarm (upon a specific application trigger). A third category in the
Application Traps is the heartbeat trap.
The Prime Home SNMP
traps (common Alarms) structure is as follows:
Application Traps (OID .220.127.116.11.4.1.10799.2000.1.1.1)
applicationThresholdAlarm (OID .18.104.22.168.4.1.10799.2000.1.1.1.1)
applicationEventAlarm (OID .22.214.171.124.4.1.10799.2000.1.1.1.2)
applicationHeartbeat (OID .126.96.36.199.4.1.10799.2000.1.1.1.3)
Network Traps (OID .188.8.131.52.4.1.10799.2000.1.1.2)
Threshold Alarm is sent when an application KPI exceeds its defined thresholds.
The thresholds are pre-configured values in the Prime Home Application. The
alarm can also be sent when a Household topology job exceeds a pre-configured
value. The notificationAlarmId (OID 184.108.40.206.4.1.10799.2000.1.2.1) is the unique
identifier for the alarm which is sent through this trap. The
notificationEntityId (OID 220.127.116.11.4.1.10799.2000.1.2.2) has a string value
representing the entity which caused the alarm.
For KPI threshold
crossing, the notificationEntityObjectIdentifier (OID
18.104.22.168.4.1.10799.2000.1.2.3) will display the KPI's OID for which the
threshold was crossed.
An Application Event
Alarm is sent when a particular event occurs in the application (for example:
server down or household topology process which failed). The value of
notificationAlarmId will identify the type of event that occurred (e.g. server
down). The value of notificationEntityId will identify the observer entity
(e.g. service layer node with a certain IP).
Heartbeat is a keep-alive indication, sent every 5 minutes to the NMS system to
let the NMS know that the service is up and running.
The Network Threshold
Alarm is CPE related. It is sent when a cross device alert is identified on a
group of CPEs. A cross device alert indicates a common alert identified on a
group of CPEs. It is sent when a certain amount of devices in the group have an
error that is connected with this common alert.
The value of the
notificationAlarmId object in this case will point to the exact type of alert
that was identified on the group of devices. The value of notificationEntityId
will point at the name of the observed group.
