Configure the Sorter transformation tracing level to control the number and type of Sorter error and status messages the Integration Service writes to the session log. At Normal tracing level, the Integration Service writes the size of the row passed to the Sorter transformation and the amount of memory the Sorter transformation allocates for the sort operation. The Integration Service also writes the time and date when it passes the first and last input rows to the Sorter transformation.
If you configure the Sorter transformation tracing level to Verbose Data, the Integration Service writes the time the Sorter transformation finishes passing all data to the next transformation in the pipeline. The Integration Service also writes the time to the session log when the Sorter transformation releases memory resources and removes temporary files from the work directory.
