Event Definitions

Events Events Events

All event data is stored in the Database Schema in a relational database. As Untangle and applications process traffic they create Event objects that add and modify content in the database. Each event has it's own class/object with certain fields that modify the database in a certain way.

The list below shows the classes used in the event logging and the attributes of each event object. These can be used to add alerts in Reports or for other event handling within Untangle.
