Elements

The probe breaks event data down into tokens and parses them into elements. Elements are used to assign values to ObjectServer fields; the field values contain the event details in a form that the ObjectServer understands.

The following table describes the elements that the probe generates. Not all the elements described are generated for each event. The elements that the probe generates depend on the event type.

Table 1. Elements
Element name	Element description
`$additionalInfo`	This element displays additional information about the alarm.
`$additionalText`	This element displays a brief description of the problem being reported by the alarm.
`$CTP`	This element displays the Connection Termination Point.
`$domain_name`	This element displays the Domain name from which the event was sent.
`$edgePoint`	This element indicates whether the alarm relates to a PTP that is not the end point of an inner topological link.
`$emsTime`	This element displays the time at which the event was reported by the EMS system.
`$Equipment`	This element displays the layer to which the alarm applies.
`$EquipmentHolder`	This element displays the name of the object reporting the alarm as given in the EMS user interface.
`$event_name`	This element displays the probable cause as given in the EMS user interface.
`$event_type`	This element displays the time at which the error occurred in the network element.
`$isClearable`	Indicates whether the event is clearable.
