Integration Service uses the tracing level set in the mapping.
Integration Service logs initialization information, error messages, and notification of rejected data.
Integration Service logs initialization and status information, errors encountered, and skipped rows due to transformation row errors. Summarizes session results, but not at the level of individual rows.
In addition to normal tracing, the Integration Service logs additional initialization details, names of index and data files used, and detailed transformation statistics.
In addition to verbose initialization tracing, the Integration Service logs each row that passes into the mapping. Also notes where the Integration Service truncates string data to fit the precision of a column and provides detailed transformation statistics.
When you configure the tracing level to verbose data, the Integration Service writes row data for all rows in a block when it processes a transformation.
