Mikael Ståldal commented on LOG4J2-1694: ---------------------------------------- Thanks. That is a valid use case. I have a similar use case myself, and use GelfLayout which has this functionallity: {code} <GelfLayout host="user"> <KeyValuePair key="environment" value="prod"/> <KeyValuePair key="application" value="whatever"/> </GelfLayout> {code} So I guess you would like something similar for JsonLayout? Maybe you can use GelfLayout instead of JsonLayout? https://www.elastic.co/guide/en/logstash/current/plugins-inputs-gelf.html > Allow to easily add fields with fixed values to JSON output > ----------------------------------------------------------- > > Key: LOG4J2-1694 > URL: https://issues.apache.org/jira/browse/LOG4J2-1694 > Project: Log4j 2 > Issue Type: Improvement > Components: Layouts > Affects Versions: 2.7 > Reporter: Raimar Falke > Labels: extra-field, json > > The Logback JSON Encoder has a feature which allows to specify JSON fields > with fixed values.
