Subject Re: Custom JSONLayout
Date Fri, 14 Aug 2020 12:18:57 GMT
So far I have looked at the logstash layout  (
https://github.com/vy/log4j2-logstash-layout). It seems it doesn't work
properly for my use case.

Basically  if I have key,value pairs I log them into the LogEvent message
field, then I parse them while generating JSON objects. The key,value pairs
are not known in advance; sometimes they are null; If the keys are null, I
don't want to log them at all.  Are there any other ways to do this?
