We have existing application.yml in our src/main/resources dir, and I added:

logging:
  level:
    ROOT: TRACE

Because we get tens of thousands of DEBUG lines when we start the app, its impossible to see errors.

However, when we set the level to TRACE, it still show all DEBUG lines, it doesnt seem to have any effect. We have nothing on the startup command line which overrides this.

WE are running it in intellij. Not sure if that makes any difference.

Any ideas what could be blocking log level config?

We are using the standard spring-boot logback.

Not sure what version of spring boot we are using, but its old (not 3) with java 8.
