The Data Collection, Analytics, and Events (DCAE) subsystem, in conjunction with other OpenECOMP components , provides FCAPS (fault, configuration, accounting, performance, security) functionality. DCAE gathers performance, usage, and configuration data about for the OpenECOMP systemmanaged environment. This 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.
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.
*****
The primary functions of the DCAE subsystem are to
- Collect, ingest, transform and store data as necessary for analysis
- Provide a framework for development of analytics, and toEnable
These two primary functions enable closed-loop responses to events or other conditions by various OpenECOMP components.
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).
