How to add username,clientId log attribute in Logout log message?

Hi,
i want to see username,client attribute in logout message. currently we are getting below logs attributes from keycloak logs when user logout successfully. is it possible to add ?

2019-11-19 18:19:46,351
INFO [org.keycloak.events] (default task-2)
type=LOGOUT,
realmId=Test,
clientId=null,
userId=test_id,
ipAddress=0.0.0.0,
redirect_uri=“testuri”

apart from above attributes i want get one more attribute i.e username and clientId has some value instead of null.

Here i’m getting username and clientId for LOGIN success logs. the same attributes we required for LOGOUT success as well.
