Percona has developed an Audit Log feature that is now included in Percona Server since the recent 5.5 and 5.6 releases. This implementation is alternative to the MySQL Enterprise Audit Log Plugin: Percona re-implemented the Audit Plugin code as GPL as Oracle’s code was closed source. This post is a quick introduction to this plugin.
There are two ways to install the Percona MySQL Audit Plugin:
INSTALL PLUGIN audit_log SONAME 'audit_log.so';
or in my.cnf
