The Data Collection, Analytics, and Events (DCAE) subystem, in conjunction with other OpenECOMP components, provides FCAPS (Fault Configuration Accounting Performance Security) functionality. DCAE supports closed-loop control and higher-level correlation for business and operations activities. It is the ecosystem component that supports analytics and events: it collects performance, usage, and configuration data; provides computation of analytics; aids in troubleshooting; and publishes events, data and analytics (for example, to policy, orchestration, and the data lake). DCAE provides the infrastructure for collection of autonomous events from the network and other cloud components, making them available to subscribing applications, including business support system (BSS) and operational support system (OSS) applications.
The DCAE environment forwards usage and other information that can be used by the BSS to generate billable events and other events and records. The BSSs obtain the data from DCAE distribution channels or from the data lake. For example, the billing function in a BSS can support near real-time balance management by receiving streaming analytics from DCAE.
Usage and event management BSSs can be created as applications on top of the DCAE environment as well as applications outside DCAE. These applications can collect customer events and perform mediation of the usage and events to downstream BSSs or OSSs (Operational Support Systems). BSSs can also collect network events such as bill-impacting configuration changes, consumption or any new bill-impacting network product or service which can in turn be used for various purposes such as rating, balance management, and charge calculations.
