How do I set the logging level in Quarkus?

Question

I would like to change the logging level of my Quarkus application.

How can I do that either from the configuration file or at runtime?

Answer 1

The property that controls the root logging level is quarkus.log.level (and defaults to INFO).

This property can be set either in application.properties or can be overridden at runtime using -Dquarkus.log.level=DEBUG.

You can also specify more fine grained logging using quarkus.log.category.

For example for RESTEasy you could set:

quarkus.log.category."org.jboss.resteasy".level=DEBUG
