The debug logging option is used for support purposes only and is disabled by default.

When enabling this option, the messages are written to the Tomcat server logs on the application server machine. You can find them in the /data/logs/tomcat/ installation directory.

Debug logs are not indexed and should not affect the performance but they can take significant space. It applies to large databases, file systems and Business Intelligence servers.

When you use this option for testing or reporting a ticket, you should disable it once finished. The option is disabled automatically when you restart the application server.

Before you begin

You have been assigned a global role with the Application Administration capability.


  1. Go to MANAGE > System.
  2. In the Debug logging field, select Enable from the drop-down list.

    When enabling the option, it shows additional information such as Object ID or Stable ID in the object pages and the Properties panel. Other internal information can also appear such as Lineage Options which are only for internal debugging purposes.
