DCAE TCA design for Enrichment
Besides configuration for TCA processing, TCA configuration model will be enhanced to support following new configuration
- RESTProxyHost, RESTProxyPor (this will be defined part of TCA app_config to indicate A&AI host/port (or MSB host/port) to be used for enrichment. This value will be preset into blueprint for demo setup)
- Configurable cache time (to avoid repeated A&AI query)
- Per CL flow
- controlLoopSchemaType = VM|VNF
- closedLoopEventStatus= ONSET | ABATED
Enrichment flow (VM enrichment is stretch goal for R1)
- When new CL condition is met
- invoke A&AI to check vnf (generic-vnf object lookup)
If generic-vnf object lookup is successful
- Set/override fields based on new CL structure and set target-type and AAI setting based on generic-vnf object
If no match from A&AI – proceed to vm based check
- Invoke A&AI to check vserver (involves two additional AAI API call 1) get vserver link 2) query vserver object)
If vserver object lookup is successful
- Set/override fields based on new CL structure and set target-type and AAI setting based on vserver object
If no match from A&AI – proceed to configuration model based setting.
- Use configuration model identified “controlLoopSchemaType” to set CL event (structure as we have currently)
