Java CI

Keycloak JSON Log Eventlistener

Primarily written for the Jboss Keycloak docker image, it will output Keycloak events as JSON into the keycloak server log.

Tested with Keycloak version 12.0.1 Compatible Java 11

Dockerfile implementation

COPY ./jsonlog-event-listener.jar /opt/jboss/keycloak/standalone/deployments/jsonlog-event-listener.jar

Configuration

Change the default log prefix

If you want to change the default log prefix (which is "JSON_EVENT::"), set the following environmental variable:

KEYCLOAK_JSONLOG_PREFIX

.. for example:

sudo docker run -it --rm -v "$(pwd)/jsonlog-event-listener.jar:/opt/jboss/keycloak/standalone/deployments/jsonlog-event-listener.jar" -e 'KEYCLOAK_USER=admin' -e 'KEYCLOAK_PASSWORD=admin' -e 'KEYCLOAK_JSONLOG_PREFIX=FOO' -p 8080:8080 jboss/keycloak:8.0.1

Once the event handler is enabled for the realm (in the admin console see Events -> Config), you should see something like this in the server log:

16:30:11,662 INFO  [org.keycloak.events] (default task-6) FOO{"type":"ADMIN_EVENT","operationType":"CREATE","realmId":"master","clientId":"01b98c9f-a2c3-418a-9c5e-a766cd51c4a7","userId":"6f87b3d2-108f-4234-8fd2-9fdccf700fce","ipAddress":"172.17.0.1","resourceType":"USER","resourcePath":"users/633ff1ce-a695-4c07-a083-1af595a839e8"}
16:30:18,063 INFO  [org.keycloak.events] (default task-8) FOO{"type":"ADMIN_EVENT","operationType":"ACTION","realmId":"master","clientId":"01b98c9f-a2c3-418a-9c5e-a766cd51c4a7","userId":"6f87b3d2-108f-4234-8fd2-9fdccf700fce","ipAddress":"172.17.0.1","resourceType":"USER","resourcePath":"users/633ff1ce-a695-4c07-a083-1af595a839e8/reset-password"}

Log user groups and attributes

If you want to log user's attributes and/or groups, set:

KEYCLOAK_JSONLOG_SHOW_GROUPS="true"
KEYCLOAK_JSONLOG_SHOW_ATTRIBUTES="true"

See above for activation with docker run, example output:

17:19:46,209 INFO  [org.keycloak.events] (default task-3) JSON_EVENT::{"type":"LOGIN","realmId":"myrealm","clientId":"test.client","userId":"10b2f010-6d87-4ece-aecd-61e7fe3bde3b","userGroups":["Group1"],"userAttributes":{"gender":["Other"],"grade":["example_grade"],"birth_year":["1998"]},"ipAddress":"192.168.3.3","auth_method":"openid-connect","auth_type":"code","redirect_uri":"https://test.app/oauth/callback","consent":"no_consent_required","code_id":"629888b4-49eb-4659-93da-32fc1ce73abd","username":"sam"}
