Data Integration generates log files to help you monitor running, failed, and completed jobs. You can access some of the log files from the All Jobs, Running Jobs, andMy Jobs pages, and from the job details.
Data Integration generates the following types of log files:
Session log file
Data Integration generates a session log file for each job. This log gives you a high level view of the time spent for different operations.
The session log provides mapping compilation time, translation time, simplification time, optimization time, total time to create the LDTM, Spark task submission time, Spark task [InfaSpark0] execution start and end time, and Total time to perform the LDTM operation.
If a job fails, analyze the session log file first to help you troubleshoot the job.

The reject file contains information about each rejected target row and the reason that the row was rejected. Data Integration saves the reject file to the following default folder:
