Tracing Levels

When you configure a transformation, you can set the amount of detail that the Data Integration Service writes in the log.
By default, the tracing level for every transformation is Normal. Change the tracing level to a Verbose setting when you need to troubleshoot a transformation that is not behaving as expected. Set the tracing level to Terse when you want the minimum amount of detail to appear in the log.
Configure the following property on the Advanced tab:
Tracing Level
Amount of detail that appears in the log for a transformation.
The following table describes the tracing levels:
Tracing Level
Description
Terse
Logs initialization information and error messages and notification of rejected data.
Normal
Logs initialization and status information, errors encountered, and skipped rows due to transformation row errors. Summarizes mapping results, but not at the level of individual rows.
Default is normal.
Verbose Initialization
In addition to normal tracing, logs additional initialization details, names of index and data files used, and detailed transformation statistics.
Verbose Data
In addition to verbose initialization tracing, logs each row that passes into the mapping. Also notes where string data was truncated to fit the precision of a column and provides detailed transformation statistics.
When you configure this tracing level, row data for all rows in a block are written to the log when a transformation is processed.
