Re: [logback-user] Java programmatic configurations

9 Jul 2012

      Hi Tony,

Thanks for your answer. Is there a way to make my application log to be
save in separate syslog file? Like with name MyApps. Sorry from posting the
same question repeatedly, because I just join this group and I thought my
first email didn't reach this group mail.

Thanks.

Hi,
What is the equivalent programmatical java code for below logback.xml
configuration :
<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <!-- encoders are assigned the type
ch.qos.logback.classic.encoder.PatternLayoutEncoder
            by default -->
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger -
%msg%n</pattern>
        </encoder>
    </appender>
<appender name="SYSLOG"
class="ch.qos.logback.classic.net.SyslogAppender">
*        <syslogHost>myhost</syslogHost>*
*        <facility>USER</facility>*
*        <suffixPattern>[%thread] %logger *%msg</suffixPattern>
    </appender>
<root level="debug">
        <appender-ref ref="SYSLOG"/>
        <appender-ref ref="STDOUT"/>
    </root>
</configuration>
Thanks.
Hi Martinus,
This doesn't directly answer your question, but it provides a solution if
your goal is to configure logback from code instead of logback.xml... You
can load the configuration XML into a string and feed that to a
JoranConfigurator, as in the example below.
Btw, please refrain from posting the same question repeatedly. :)
Hope that helps,
Tony
