    Description

      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:

      <encoder class="net.logstash.logback.encoder.LogstashEncoder">
        <customFields>{"appname":"myWebservice","roles":["customerorder","auth"],"buildinfo":{"version":"Version 0.1.0-SNAPSHOT","lastcommit":"75473700d5befa953c45f630c6d9105413c16fe1"}}</customFields>
      </encoder>
      

      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.
