New system properties have been introduced to AS7 which allow setting of the configuration history length and the number of days they are kept. These properties need to be documented properly. See AS7-4931.

The default value of jboss.config.current-history-length is 100 and the default value of jboss.config.history-days is 30.

Here is an example configuration:

..
    </extensions>

    <system-properties>
        <property name="jboss.config.current-history-length" value="50"/>
        <property name="jboss.config.history-days" value="15"/>
    </system-properties>

    <management>
