The Data Collection, Analytics, and Events (DCAE) subsystem, in conjunction with other OpenECOMP components, provides Fault Configuration Accounting Performance Security (FCAPS ) functionality. DCAE supports closed-loop control and higher-level correlation for business and operations activities. It supports analytics and events: it collects FCAPS (fault, configuration, accounting, performance, security) functionality. DCAE gathers 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 about the OpenECOMP system. This data can then be fed to various analytic programs, and if anomalies or significant events are detected, the results can trigger appropriate actions, such as publishing to other OpenECOMP components such as Policy, orchestration, or the data lake. DCAE supports closed-loop control and higher-level correlation for business and operations activities. It also 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.
