Dee Vinci commented on LOG4J2-3025:
-----------------------------------
[~ckozak] Thanks for the prompt reply:)
yes Logger.info(Object) works but it would require change in all logs logged in
our whole codebase
as we have followed the ParameterizedMessage convention.
also as we have shared our error log messages to third parties and have set
alerts on the same,
so we cant change the log message order and structure
so migrating to Json Layout would mean changing
LOG.info("Logging testDto {} Inputparam1 {} Inputparam2 {}", testDto, param1,
param2);
to
LOG.info("Logging testDto");
LOG.info(testDto);
LOG.info(" Inputparam1 ");
LOG.info(param1);
LOG.info(" Inputparam2 ");
LOG.info(param1);
which doesn't look that good..right
it would be great if we could change the escaped json behaviour by doing some
changes in xml configuration
kindly look into it once..
thanks

> Priority: Major

> Our organization is using log4j2 version 2.11.2 and xml based configuration,

> 2.) In Pattern Layout while logging, the prefix string of some of the logs
> was truncated so we had added {{%.-60000m%}} in pattern Layout configuration
> so that the beginning of log message is not truncated. Do we have a similar
> plugin or workaround in Json Layout.
> need to resolve this as early as possible so kindly revert in case of any
> lead or any extra information needed so that we can resolve this
> Thanks.
