You can easily create a custom layout object by creating a cfc that extends our abstract layout object: logbox.system.logging.Layout and implementing a format() method. Below you can see the method signature:
<--- format --->
<cffunction name="format" output="false" access="public" returntype="string" hint="Format a logging event message into your own format">
<cfargument name="logEvent" type="logbox.system.logging.LogEvent" required="true" hint="The logging event to use to create a message.">
All you need to do is inspect the logging event and create your very own message and then return it back. That's it! You thought there was more?
