Here is how everything is configured
JBoss syslog appenders (rsyslog appender shown as reference only)
----------------------------------------------------------------------------

<!-- Syslog events to rsyslog-->
<appender name="RSYSLOG" class="org.apache.log4j.net.SyslogAppender">

<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d{ABSOLUTE}] %-5p [%c]
%m%n"/>
</layout>
</appender>
<!-- Syslog events to nxlog -->
<appender name="NXLOG" class="org.apache.log4j.net.SyslogAppender">

The rsyslog and local file system logs show the hostname of the server, the
nxlog appender is showing the ip address in the logs and writing the log
file name as 'ip_address.log' instead of 'hostname.log'

Subject: Re: [nxlog-ce-users] Hostname resolution
Hi,
Hostname comes from two sources, it can be already present in the (sys)log,
otherwise the gethostname(2) system call is used to retrieve and set it.
Since you did not provide any information on how your input is processed and
what it looks like, it's kinda hard to help.
Regards,
Botond
