Keycloak Events Logging Revised

It’s been now 3 years since I wrote about Keycloak events and how to see them occurring in the log output of the server. As the basic concept of how, or, on which log level they are written to the logger still remains the same, the way it will be configured has been changed completely with the Quarkus distribution.

In my mentioned post, I describe two ways of how to configure the logging. Meanwhile, I prefer setting the proper log level on the jboss-logging event listener over reconfiguring the log level for the org.keycloak.events package logger.

Depending on the way you configure you environment, you have these options:

Using the .conf configuration file

spi-events-listener-jboss-logging-success-level=info
spi-events-listener-jboss-logging-error-level=warn

Using the command line arguments

--spi-events-listener-jboss-logging-success-level=info
--spi-events-listener-jboss-logging-error-level=warn

Using environment variables

KC_SPI_EVENTS_LISTENER_JBOSS_LOGGING_SUCCESS_LEVEL=info
KC_SPI_EVENTS_LISTENER_JBOSS_LOGGING_ERROR_LEVEL=warn
