How to correctly map the payload of a log.atInfo to a structured log

[bashout]

I'm using logback and I believe your library would allow me to map a logs payload to the output. I'm trying to use the payload part of the log to pass an event.

Something like
log.atInfo { message = "test" payload = buildMap(capacity = 1) { put(LogEvent.Event, LogEvent.Test_Event}}

Your wiki or docs don't really clearly tell me how I can access this payload value.

Thank you for reporting an issue. See the wiki for documentation and slack for questions.

I appreciate the article, still having the same issue however. I've already configured structured logging using the logstash-logback-encoder and have a encoder pattern that pulls out things like a correlationID from the MDC for example and this is functional.

However the article suggests that any key value pair added will be automatically rendered as a structured log. Appreciate this may be a "my config" issue, but there's not a lot of clear guidance. My encoder looks like this:

{
        "timestamp": "%date{yyyy-MM-dd'T'HH:mm:ss.SSSZ}",
        "severity": "%p", 
        "exception": "%rEx",
        "logger": "%logger",
        "message": "%message",
        "correlationId": "%X{correlationId}"
}

I've tried both permutations of "log_event_code": "%X{log_event_code}" and "log_event_code": "" where the key in the payload where I log is 'log_event_code' to see if it required a placeholder, however each to no avail.

Am I missing something obvious?

I don't think it's an issue related to kotlin-logging. You can try to debug it and see how it is decoded.

Appreciate the feedback. I'm sure you're right. I'll mark this as resolved
