5. Troubleshooting

When you encounter problems with the operation of the Keycloak app, this chapter providers information where you can look closer into and to get an impression about what is going wrong.

5.1. Log files

The Keycloak app produces different logging information in different places.

/var/log/univention/appcenter.log

Contains log information around activities in the App Center.

The App Center writes Keycloak relevant information to this file, when you run app lifecycle tasks like install, update and uninstall or when you change the app settings.

/var/log/univention/join.log

Contains log information from join processes. When the App Center installs Keycloak, the app also joins the domain.

Keycloak Docker container

The app uses the vanilla Keycloak Docker image. The App Center runs the container. You can view log information from the Keycloak Docker container with the following command:

$ univention-app logs keycloak

Keycloak Admin Console

Offers to view event logs in Events in the Manage section. Administrators can see Login Events and Admin Events. For more information, see Keycloak Server Administration Guide: Configuring auditing to track events [5].

5.2. Debugging

To increase the log level for more log information for the Keycloak app, see keycloak/log/level.

This log level only affects the log information that Keycloak itself generates and writes to the Docker logs. The App Center sets the Docker container’s KEYCLOAK_LOGLEVEL environment variable to the value of keycloak/log/level.
