Audit logging uses Talend LogServer for storing and displaying audit logs, although it treats them separately from normal logs (in particular, it stores them in a separate index and provides separate dashboard).
On the application side, it provides a dedicated Audit Logging API, which builds its own pipeline using the same framework as the application (but does it independently of normal logging configuration). For more information about Audit Logging API, see https://github.com/Talend/daikon/tree/master/daikon-audit.
Before enabling the feature, make sure the
