I checked the configuration file and couldn’t find the user session duration config. It’s possible to change this config ? We need a way to logoff the user after 30 minutes of inactivity

This is controlled by the REDASH_SESSION_EXPIRY_TIME environment variable. You can specify it in seconds. The default is 60 * 60 * 6 which is six hours. For thirty minutes you can set the variable to 1800 and then restart your services.
