• Analyze what was causing the performance problem without having to
watch the dynamic indicators continuously.

You can record the link test measurements to a log file, and use this log file
to more fully analyze the link quality. The measurement data can be logged
automatically at regular intervals or manually upon user-command.
For more information on log files, see Logging Measurement Data (page 92).
