Keycloak : How to set log level via command line
2021, Nov 09
Keycloak is an open source identity and access management solution (SSO). It’s a pretty complete solution but like all complexe application is difficult to debug.
By default the log level of Keycloak is set to INFO but you have different approaches to change it :
- config file (if you are using an installed instance)
- environment parameters (if you use docker)
- via the jboss command line
In this post we will explain how to do it by using the command line. The big difference between the first two and the cli is that you don’t need to restart the application !
Connect to your application in SSH
ssh username@servername
Go to your Keycloak the installation folder in the bin folder
In my case it is l.ocated in the folder /srv/keycloak/bin
Run the jboss command line file
./jboss-cli.sh
Connect to your local instance of Keycloak
connect
Set the new log level
/subsystem=logging/logger=org.keycloak.services.resources:add(level=DEBUG)
The log levels available are :
- ALL
- DEBUG
- ERROR
- FATAL
- INFO
- OFF
- TRACE
- WARN
