Re: [Wrapper-user] Please add "JSON" to logging format

Thank you for your email and your suggestion to add JSON as possible log
format. This is indeed an interesting idea.

Actually we did not plan to add support for json format in the near future,
but we will surely keep the idea in mind and discuss about it. The ability
to easily process and parse the json format is indeed a good point,
although as pointed by Karthik, other formats would also have this feature.

In the current versions, we try to keep the logging features of the Wrapper
easy to configure for the users and we generally advise to use tools such
as log4j for specific needs. Help on how to output JSON with log4j can
easily be found on the internet.

Please let us know if you have any other remarks or suggestions.

Best Regards,

Maxime
