The Logical Domains Manager uses the Oracle Solaris OS auditing feature to examine the history of actions and events that have occurred on your control domain. The history is kept in a log that tracks what was done, when it was done, by whom, and what was affected.
You can enable and disable the Oracle Solaris OS auditing feature. Use the audit command. See the audit(1M) man page and Managing Auditing in Oracle Solaris 11.3 .
