How should the developer update the logging configuration in order to enable this package specific...

To enable package-specific debugging for the org.apache.cxf package, you need to update the logging configuration in the Mule application's log4j2.xml file. The steps are as follows:

Open the log4j2.xml file in your Mule application.

Add an AsyncLogger element with the name property set to org.apache.cxf and the level set to DEBUG. This configuration specifies that only the logs from the org.apache.cxf package should be logged at the DEBUG level.

Save the changes to the log4j2.xml file.

Redeploy the updated Mule application to the CloudHub production environment to apply the new logging configuration.

This approach ensures that only the specified package's logging level is changed to DEBUG, minimizing the potential performance impact on the application.
