SLF4J / SLF4J-600 [Resolved] .addKeyValue() log-requests are not getting logged ============================== Here's what changed in this issue in the last few minutes. There is 1 comment. View or comment on issue using this link https://jira.qos.ch/browse/SLF4J-600 ============================== 1 comment ------------------------------ Ralph Goers on 23/Sep/23 6:33 I just took a look at the code and it is adding the key/value pairs to the ThreadContextMap instead of building a MapMessage. The SLF4J documentation says {code:java} The key-value pair variant of the API stores the key-value pairs as separates objects. The default implementation currently in the org.slf4j.Logger class prefixes key-value pairs to the message. Logging backends are free and are even encouraged to offer a more customizable behaviour. {code} Given that the API says that what happens with key/value pairs is implementation specific I'd hesitate to classify this as an error. Adding %X to your pattern should cause them to be included. I can't speak to what EcsLayout does as that is not provided by Log4j but JsonTemplateLayout would allow the items to be included in the JSON. Despite this I will open a discussion on the Log4j dev list to determine if what we are doing is really the correct behavior. ============================== This message was sent by Atlassian Jira (v9.6.0#960000-sha1:a3ee8af)
