You can configure the level of logging using the Teradata Logging Preferences. Logging levels for the Teradata Log console and the Teradata log file are controlled separately.
For example, you can change the logging level for the Teradata log file which enables debug logging for all of Teradata Studio plug-ins, with log messages going to the teradata.log file.
You can also add a Logger for more localized logging. For example, you can log debug messages for only the com.teradata.datatools.dtp.catalog plug-in.
