Audit Log Filter file format overview

When an auditable event occurs, the component writes a record to the log file.

After the component starts, the first record lists the description of the server and the options at startup. After the first record, the auditable events are connections, disconnections, SQL statements executed, and so on. Statements within stored procedures or triggers are not logged, only the top-level statements.

If files are referenced by LOAD_DATA, the contents are not logged.

Set with the audit_log_filter.format system variable at startup. The available format types are the following;

Format Type Command Description
XML (new style) audit_log_filter.format=NEW The default format
XML (old style) audit_log_filter.format=OLD The original version of the XML format
JSON audit_log_filter.format=JSON Files written as a JSON array

By default, the file contents in the new-style XML format are not compressed or encrypted.

Changing the audit_log_filter.format, you should also change the audit_log_filter.file name. For example, changing the audit_log_filter.format to JSON, change the audit_log_filter.file to audit.json. If you don’t change the audit_log_filter.file name, then all audit log filter files have the same base name and you won’t be able to easily find when the format changed.
