Class The custom line layout class.

This class must implement org.apache.logging.log4j.core.layout.PatternLayout and must be available in the runtime classpath.

The class needs 2 constructors:

  • One with no argument
  • One with a single String argument, which receives the value of the Arguments field.
Arguments A String parameter used for the custom line layout class, if required:
  • To use the constructor that requires an argument, specify the argument
  • To use the constructor that does not expect an argument, leave the field empty.
Note: To override the default TIBCO BusinessEvents CDD logging properties, see Overriding the Default Logging Mode.

Additional log settings can be added to the Processing Unit tab Properties, see Processing Units Configuration Settings.
