Logging Additional Fields in Quarkus with JSON

I am currently attempting to change our logs format in Quarkus from String to JSON with some additional fields that are important for our monitoring and data analysis in elastic/kibana.

So far I have added this dependency as specified in the official documentation

<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-logging-json</artifactId>
</dependency>

https://quarkus.io/guides/logging

That changed the log format from a normal String to a full JSON format.

For example:

{"timestamp":"2022-09-05T13:30:09.314+01:00","sequence":24441,"loggerClassName":"org.jboss.logging.Logger","loggerName":"org.com.Controller","level":"INFO","message":"Test","threadName":"executor-thread-0","threadId":354,"mdc":{},"ndc":"","hostName":"hostname","processName":"test.jar","processId":9552}

My question is, how do I add additional fields to this log output, for instance I need to add and additional json field called 'pattern' with a value extracted from the code each time. The final json output will look like this:

{"timestamp":"2022-09-05T13:30:09.314+01:00","sequence":24441,"loggerClassName":"org.jboss.logging.Logger","loggerName":"org.com.Controller","level":"INFO","message":"Test","threadName":"executor-thread-0","threadId":354,"mdc":{},"ndc":"","hostName":"hostname","processName":"test.jar","processId":9552, "pattern" :"test-pattern"}

I tried the following as specified in the documentation:

quarkus.log.file.json.additional-field.pattern.value=test-value
quarkus.log.file.json.additional-field.pattern.type=string

But this didn't show anything, and Im not sure how to use it programmatically,

You might be able to solve your problem using the quarkiverse logging json extension using their JsonProvider

https://github.com/quarkiverse/quarkus-logging-json

The quarkiverse logging json extension is much more flexible/extensible than the standard quarkus logging json packages, since you can add fields to the json log programatically, instead of in hard coded configuration

Example configuration

quarkus.log.console.json.additional-field."EXTRA".value=test-value
quarkus.log.console.json.additional-field."EXTRA".type=string

quarkus.log.file.json.additional-field."EXTRA".pattern.value=test-value
quarkus.log.file.json.additional-field."EXTRA".pattern.type=string

Should have double quotes. and example output

{"timestamp":"2022-09-18T14:37:37.687+01:00","sequence":1548,"loggerClassName":"org.jboss.logging.Logger","loggerName":"org.acme.GreetingResource","level":"INFO","message":"Hello","threadName":"executor-thread-0","threadId":101,"mdc":{},"ndc":"","hostName":"mintozzy-mach-wx9","processName":"code-with-quarkus-dev.jar","processId":133458,"EXTRA":"test-value"}

for full working example check
