With the following steps you can enabled details logs on booting the AJP connector.
**Configure the JUL Logger properties**
in the JRE that runs the Axon.ivy Engine. E.g. `[engine]/jre/lib/logging.properties`. At the end of the file add: `org.apache.tomcat.util.net.NioEndpoint.level = ALL`

**Configure Log4j**
in `[engine]/configuration/log4jconfig.xml`. Add the following lines somewhere between the `<log4j:configuration>` tags:
<appender name="AjpLog" class="org.apache.log4j.DailyRollingFileAppender">
<param name="Threshold" value="ALL"/>
<param name="File" value="${user.dir}/logs/ajp.log"/>
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<layout class="ch.ivyteam.log.layout.IvyLog4jLayout">
<param name="DateFormat" value="HH:mm:ss.SSS"/>
</layout>
</appender>
<category name="org.apache.coyote.ajp.AjpNioProtocol" class="ch.ivyteam.log.Logger">
<priority value="ALL"/>
<appender-ref ref="AjpLog"/>
</category>
<category name="org.apache.tomcat.util.net.NioEndpoint" class="ch.ivyteam.log.Logger">
