Aggregation and Correlation Engine 2 (ACE2)

The ACE2 engine is event-driven. This engine receives information from the database on an ongoing basis. ACE2 has a faster response rate to events than the ACE1 engine primarily because it does not work in cycles. Due to the event-driven approach, the time from adapter execution to customer report is shorter than in the ACE1 engine.

ACE2 is constructed of two main segments:

• The manager is responsible for handling all the calculation and recalculation decisions.
• The workers are responsible for calculating the metrics, based on the instructions of the manager.

The manager holds an instruction queue for metric calculations referred to as the mission queue. The workers calculate metrics from the queue without any affinity. This method gives the system automatic load balancing because there is no need to assign metrics to instances.

ACE2 only performs necessary calculations. Overhead is reduced because when there is nothing to calculate, the system does not perform redundant calculations. ACE2 consumes minimum resources.

The ACE2 engine cannot process the following:

• Metrics that use the forecast feature.
• Metrics registered by Event type.
• Clustered metrics that use static clustering

Note: Send metrics registered by event to the ACE1 engine. ACE2 does not recognize these metrics.
