Currently the default folder is /opt/apache-tomcat-8.5.37/kafka-data which is not a monitored folder for disk space.

Hence would like to change the folder to a monitored folder to ensure adequate space.

There is a post link below which mentions that the folder location can be changed by adding a DSS.

Updated the DSS, restarted Pega and Kafka processes. Still its updated in the default tomcat folder.

Appreciate if anyone knows any additional steps needed for this to work.
