The HPE Aruba Networking Network Analytics Engine (NAE) is tightly integrated with the AOS-CX operating system and uses a built-in Time Series Database to retain historical monitoring information. HPE Aruba documentation states explicitly that the NAE includes a built-in time series database in which data about monitored switch resources is collected automatically and made available to NAE agents. Aruba Networking
This architecture enables NAE agents to evaluate network conditions over time , rather than relying only on instantaneous state. Examples include tracking interface utilization, packet counters, environmental conditions, protocol behavior, or other switch resources and correlating changes to detect developing problems. The historical information can also be displayed as graphs through the AOS-CX Web UI. Aruba Networking
NAE scripting is based on a built-in Python interpreter , not Ruby. Aruba also describes a Python sandbox with access to the switch ' s internal database and time-series data when an agent executes actions. Aruba Networking Apache Cassandra and Firebase Realtime Database are external database technologies and are not the database component used by the AOS-CX NAE framework.
Therefore, D. Time Series Database is the correct choice.
