Hi @nononame2021 ,
You can ignore what you found. It is a backward compatibility setting.
Current SSIS logging is a run-time configuration settings for the SSIS Catalog on a server, not during development.
All logging events are automatically saved to the SSISDB database.
Available logging levels:
- None Logging is turned off. Only the package execution status is logged.
- Basic All events are logged, except custom and diagnostic events. This is the default value.
- RuntimeLineage Collects the data required to track lineage information in the data flow. You can parse this lineage information to map the lineage relationship between tasks. ISVs and developers can build custom lineage mapping tools with this information.
- Performance Only performance statistics, and OnError and OnWarning events, are logged.
- Verbose All events are logged, including custom and diagnostic events.
