Auditing your database means tracking access and changes to your data and db objects. The Audit Log Plugin has been shipped with Percona Server since 5.5.37/5.6.17, for a little over 12 months. Prior to the Audit Log Plugin, you had to work in darker ways to achieve some incarnation of an audit trail.
