Hi everybody,
we are using the log4j2 json appender to generate json logs which will be used
in graylog.
The JSON layout doesn’t fit perfectly for us, and I tried to create our own
JSON by using the RollingRandomAccessFile appender with the patternLayout and
the JSON encoding function.
This fits very good for us, but I am not able to create a field thrown_name,
like in the JSON appender.
Example of JSON Appender:
Field name: thrown_extendedStackTrace
Value: org.springframework.beans.FatalBeanException; ......... <the whole
stacktrace>
Field name: thrown_name
Value: org.springframework.beans.FatalBeanException
It is no problem to generate the whole stacktrace in patternlayout using this
code snippet: enc{%throwable}{JSON}
But how to generate a field which only includes the thrown_name of the
exception?
Thanks and greetings,
Christian
