The Data Collection, Analytics, and Events (DCAE) subsystem, in conjunction with other OpenECOMP components, gathers performance, usage, and configuration data from the managed environment. This data is then fed to various analytic programs, and if anomalies or significant events are detected, the results trigger appropriate actions, such as publishing to other OpenECOMP components such as Policy, orchestrationMSO, or the data lakeControllers.

The closed-loop responses are enabled by DCAE, in conjunction with other OpenECOMP components, by providing the ability to detect anomalous conditions in the network. Such conditions, might be, for example, fault conditions that need healing or capacity conditions that require resource scaling. DCAE gathers performance, usage, and configuration data about the managed environment, such as about virtual network functions and their underlying infrastructure. This data is then distributed to various analytic micro-services, and if anomalies or significant events are detected, the results trigger appropriate actions by other OpenECOMP components such as Policy, MSO or other orchestration components, or Controllers. In addition, the micro-services might persist the data (or some transformations of the data) in the storage lake. In addition to supporting closed-loop control, DCAE also makes the data and events available for higher-level correlation by business and operations activities, including business support systems (BSS) and operational support systems (OSS).
