Splunk v6.2 debuted the Distributed Management Console (DMC), now simply Management Console (MC) which can be configured on a Search Head. It almost completely replaces the Splunk-on-Splunk (S.O.S) and Splunk Deployment Monitor apps for most cases. The Licensing stats are gathered via a REAST API using the rest command | rest splunk_server=youSplunkLicenseMaster.local /services/licenser/pools but this is only available to admins. Read more about it here: http://docs.splunk.com/Documentation/Splunk/6.2.3/Admin/ConfiguretheMonitoringConsole.
SPECIAL NOTE: if you add your License Master as a search peer to your MC, then the License views will work, otherwise not.
