SyslogAppender and remote rsyslog server

Hello,

I send Tomcat logs to a remote rsyslog server via a SyslogAppender.

My appender configuration is the following :

<appender name="rtAppenderSyslog" class="org.apache.log4j.net.SyslogAppender">
<param name="SyslogHost" value="xx.xx.xx.xx"/>
<param name="Facility" value="local3"/>
<param name="FacilityPrinting" value="true"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d

[%t] %-5p (%c

:%L) - %m%n" />
</layout>
</appender>

The rsyslog server receives correctly the Tomcat logs but the rsyslog $hostname variable contains the IP address of the Tomcat server.

Could you tell me if it's possible to get the Tomcat server hostname instead of its IP address ?

Thanks in advance for your support.

Regards
