ETL+ Debug Levels & Logging Levels
Levels 0, 1 or 2 creates an additional log file with debug information that is saved on the hard drive (HD) of the computer hosting ETL+. ETL Debug Level 2 saves a lot more log information on the local log file.
The levels are set on the ETL+ Settings page.
See ETL+ Settings Page for how to set the levels and where to find the log files.
