In our AEM 6.3 project, we have a need to add the additional attribute in log message. Basically, we want to customize the message format. So we have created one logback file under src/main/resources/logback.xml. Content of the logfile is as follows

<configuration>  <appender name="SampleProject.log" class="ch.qos.logback.core.FileAppender"> <file>SampleProject.log</file> \<append>true</append> <encoder> <pattern>%d %-5level %X{sling.userId:-NA} [%thread] %logger{30} %marker- %msg %n</pattern> <immediateFlush>true</immediateFlush> </encoder> </appender>  <logger name="org.wc.project" level="INFO"/>  </configuration>

And under Apache Sling Logging Configuration, we have created one log configuration as follows with "same name" as appender name."SampleProject.log""info" ="org.wc.project""{0,date,dd.MM.yyyy HH:mm:ss.SSS} *{4}* [{2}] {3} {5}" 

But the customized message format is now shown in SampleProject.log. Can anybody please provide any pointers for the same.

Sling MDC Inserting Filter exposes various request details as part of MDC. But in my case, I need additional variables like Application Name, Application Version etc. MDC is limited to pre-defined variables, so how to add the custom variables in log?



I am not sure with Appender you can dump customise log in to project log file or you can specify same log file for appender as well.

You can check Slf4j MDC log option as well if helps
