About audit logging

Audit logging is an optional feature that togs messages whenever a BIG-IP system object, such as a virtual server or a load balancing pool, is confined (that is. created, modified, or deleted). The BiGIP system logs the messages for these auditing events in the file /var/log'audit

There are three ways that objects can be configured

* By user action

* By system action

* By loading configuration data

Whenever an object is configured in one of these ways, the BIG-IP system logs a message to the audit log
