By default, separate log files are created for log messages related to circuit creation and deletion. The name of the creation log file is the name of the related topology server with the “circuit-create.log” suffix. For example, OTM-SDH-TOPOLOGY-circuit-create.log. Similarly, the name of the deletion log file is the name of the related topology server with the “circuit-delete.log” suffix.

An indication within the server log file indicates each time the circuit creation processing starts and finishes so that the relative time of processing can be seen.

There is a single RECORD_ERROR message in the log file for each record that is not fully processed to success. RECORD_ERROR can be searched for in the log file to identify all of the “Fallouts”. Additional error messages may be included in the log file to give more details of the error when possible. Also, each time either process runs there are some basic statistics printed at the end of processing (number of circuits created, number of erred records, etc.).
