Log4j2 SyslogAppender / SyslogLayout and message format
Hi,
I'm trying to use the SyslogAppender and possibly the SyslogLayout but I
wanted to customise the message format so that some MDC parameters could be
added to the content of the message (e.g. by applying a pattern layout to
the 'message' portion).
Is there any way of achieving this? There used to be with Log4j 1.2.
I appreciate that this can be done with format 5424 but we're using BSD
format right now.
Thanks,

Kind regards,
Brett

I thought about this when I implemented the SyslogLayout. The problem here is that only a subset of the pattern converters should be available in the SyslogLayout since some of them are already there. What you are proposing below changes the semantics of a Layout - they have access to everything in the log event and format the entire event, not just the message field. It could certainly be possible to do what you are suggesting but I have a concern that it could be confusing.

Hi,
Specifically I'm trying to do something like:
<Syslog name="syslog" host="127.0.0.1" port="514" facility="local1"
protocol="UDP">
<!-- Here the pattern layout is only supposed to be the text / message
part of syslog record i.e. not the date/time stamp etc. -->
<PatternLayout pattern="%-40.40c %-25.25t %X %m" />
</Syslog>
Thanks,
Brett

Hello,
Can you give us a specific example of what you'd like to achieve?
Thank you,
