Customizing log4j configuration by using differential extensibility
Update the custom log4jconfig.xml file. The system overlays your changes on the application-provided log4jconfig.xml file.
About this task
Do not change any existing appender elements. Changes to
appender elements might stop the log collection process, prevent you from
exporting logs in the Self
Service, and prevent you from viewing log files in
Graylog. Do not add appender elements. The system collects log files from the
default appender elements.
