Overview

The wireless network contains a wealth of information about unassociated and associated devices. The Analytics and Location Engine (ALE) is designed to gather, process, and share information from the network through a simple and standard API. ALE includes a location engine that calculates associated and unassociated device location periodically using context streams, including RSSI readings, from WLAN controllers or Instant clusters.

For every device on the network, ALE provides the following information through the Northbound API:

Client Username

IP address

MAC address

Device type

Application firewall data, showing the destinations and applications used by associated devices.

Current location

Historical locations

Personal identifying information (PII) can be filtered out of the data, providing the option to view standard or anonymized data with or without MAC addresses, client user names, and IP addresses.

This guide describes ALE installation and configuration, ALE features, security, polling APIs, and publish and subscribe APIs.
