| Capabilities |
| ------------ |
| Data Collection Analytics and Events (DCAE) is the data collection and analysis subsystem of ONAP. |
| Its functions include among other things the collection of FCAPs data from the network entitiess (VNFs, PNFs, etc).It provides also a framework for the normalization of data format, the transportation of |
| data, analysis of data, and generations of ONAP events which can be received by other ONAP components such as Policy for |
| subsequent operations |
| like closed loops. |
| DCAE consists of DCAE Platform components and DCAE Services components. The following list shows the details of what are included |
| in ONAP R1 |
| When VM is indicated, it means that the components runs on its own VM on the platform. |
| DCAE platform is based both on virtual machines (VM) and containers. |
| |
| - DCAE Platform |
| - Core Platform |
| - Cloudify Manager (VM) |
| - Consul service (VM cluster) |
| - Extended Platform |
| - Docker Host for containerized platform components (VM). It runs the following DCAE platform micro services (containers). |
| - Configuration Binding Servive |
| - CDAP Broker |
| - Deployment Handler |
| - Policy Handler |
| - Service Change Handler |
| - DCAE Inventory-API |
| - CDAP Analytics Platform for CDAP analytics applications (VM cluster) |
| - Docker Host for containerized service components (VM) |
| - PostgreSQL Database (VM) |
| |
| note: the ONAP DCAEGEN2 CDAP blueprint deploys a 7 node CAsk Data Application Platform (CDAP) cluster (version 4.1.X), for running data analysis applications. |
| |
| - DCAE Services |
| - Collectors |
| - Virtual Event Streaming (VES) collector, containerized |
| - SNMP Trap collector, containerized |
| - Analytics |
| - Holmes correlation analytics, containerized |
| - Threshold Crosssing Analytics (TCA), CDAP analytics application |
| |
| |
