Up to CA Spectrum 10.1.1, the SNMPgtw (SNMP Gateway) probe was used to forward the CA UIM alarms to CA Spectrum. To forward the alarms, the SNMPgtw sends traps to CA Spectrum. An incoming trap is processed to generate an event on a model, and depending on the severity of the event it can generate an alarm.
CA Spectrum receives traps from CA UIM. CA Spectrum uses originating events based on AlertMap mapping to raise different event codes based on the event conditions/severity.
The CA Spectrum EventAdmin model receives events from the Southbound Gateway and transfer the event data to EventModel or device models depending on how the integration is configured. Alarms can be created from this event data.
The EventModel is a model type that represents a unique source of event data on the system that is managed by the EventAdmin application. A given EventAdmin model can contain one or many instantiated EventModels. Each event that is received through the Southbound Gateway contains information that uniquely identifies the source of that event. The EventAdmin model receives the event, finds the unique event source, and passes the event to the target destination.
In CA Spectrum 10.1.2 onward, the spectrumgtw (Spectrum Gateway) probe is used to forward the CA UIM alarms to CA Spectrum. Actually the spectrumgtw supports bi-directional integration. Alarms can be forward on both directions. To forward the CA UIM (NAS) alarms to CA Spectrum, the spectrumgtw generates alarm events through RESTful.
CA Spectrum receives alarms from spectrumgtw probe, an originating event 0x06330071, is used in Spectrum to raise events based on event conditions.
Then the CA Spectrum EventAdmin model receives events from the Southbound Gateway and transfer the event data to Event model or device models depending on how the integration is configured.
How does the spectrumgtw probe create a NAS alarm in CA Spectrum side?
