Using Enterprise Manager, you can export the audit log entries that reside in an object store. As part of the export process, you first search for the log entries you want to export, which means you can choose to export all log entries or a subset. The export process results in an XML file that you can, for example, use as input to a reporting tool, or use as the content for a Content Engine document and then declare the document as a record to archive the log.
For more information, see Export audit entries and Exporting objects in the Help for Content Engine Administration.
