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

[Y.Watanabe <na...@gm...>]

Hi. Sorry to late reply.
This is just a problem of log format choice.
I feel good json to log format, another one likes txt splitter by pipe.
And in the world, Json is the standard format. Elasticsearch,
fluentd,logstash...
I am waiting that JSW support json for one of the supported log format.
