Zilong Song updated LOG4J2-1838:
--------------------------------
Description:
Add support for appending common suffix to each line of throwable stack trace.
The suffix can be configured by patterns just like patterns used elsewhere.
For example, pattern {{%xEx\{suffix(- %mdc\{key\})\}}} will append a string
generated by pattern {{- }} and pattern {{%mdc\{key\} }}.
But throwable patterns will be automatically ignored, because they will make
the rendered result confusing. So pattern {{%xEx\{suffix(- %rEx%mdc\{key\})\}}}
has the same effect with {{%xEx\{suffix(- %mdc\{key\})\}}}, as if the nested
{{%rEx}} pattern has never appeared.
With the common suffix, the stack trace is as following: (with pattern
{{suffix(- %mdc\{key\})}}, and MDC value {{test mdc suffix}} to {{key}})
{code:title=stack trace|borderStyle=solid}
