[keycloak-dev] How to increase the log level of Keycloak

[Tech]

Dear experts,

we are working with Keycloak 2.5.1 and we configured a OIDC resource.

While we are connecting from outside, Keycloak returns a 400 (detected 
from our application), but we don't see this error reflected into the 
console and we are not able to increase the log level of Keycloak.

We checked some parameters into 
/standalone/configuration/standalone.xml, we changed the console-handler 
to "FINEST", but we still don't get any needed log.

Could you please advise?

Thanks!
