If you're running the project in the modeler, set the loglevel of the CONNECTIONBUS_UPDATE category to DEBUG. In the console menu it's something like "2: Advanced" -> "7: Set console log level" -> "X: CONNECTIONBUS_UPDATE" -> "2: DEBUG".
A higher logleval will reveal the database queries:
In application.conf set
ConsoleLogLevel = TRACE
or
ConsoleLogLevel = DEBUG
