> Key: LOG4J2-1694
> URL: https://issues.apache.org/jira/browse/LOG4J2-1694
> Project: Log4j 2
> Issue Type: Improvement
> Components: Layouts

> The Logback JSON Encoder has a feature which allows to specify JSON fields with fixed values. Link: https://github.com/logstash/logstash-logback-encoder#loggingevent_custom_global
> Example:
> {noformat}
> <encoder class="net.logstash.logback.encoder.LogstashEncoder">
> <customFields>{"appname":"myWebservice","roles":["customerorder","auth"],"buildinfo":{"version":"Version 0.1.0-SNAPSHOT","lastcommit":"75473700d5befa953c45f630c6d9105413c16fe1"}}</customFields>
> </encoder>
> {noformat}
> This is a very convenient way to specify fixed attributes like application, service or environment.
> So far I don't see such a possibility in log4j.
