-----------------------------------------
Hi [~rgoers]
Thanks for the response, It helped.
I have one more question, I am configuring my appender manually using
ConfigurationBuilder. and I was able to add the required pattern to it. see
below:
LayoutComponentBuilder layoutBuilder = builder.newLayout("PatternLayout")
.addAttribute("pattern", getLayoutconf());
But now, I need to do some customization, that we need to change the
patternlayout based on the logger name. so I looked into ScriptPatternSelector,
see below. But I am facing issues, like how we can configure this script
pattern selector manually using {*}ConfigurationBuilder{*}? please can you
share an example if any.

Thanks in advance!

> HI Team,
