Changing sensor expiration time

By default, sensors expire 168 hours after they become inactive. To change this default value:

1. Open the <controller_install_dir>/tomcat/webapps/scancentral-ctrl/WEB-INF/classes/config.properties file in a text editor.

2. Set the worker_expiry_delay property value to the number of hours to elapse after inactivity before sensors expire.

3. Save and close the config.properties file.
