The following figure depicts points in the data flow associated with key
metrics. This is not intended as a master reference for all metrics, but serves
as an aid for performing an analysis in advanced mode. For example, the
expanded portion shows the relationship between the Read M-JNL Process
Time, R-JNL Transfer and Process Time, and the End-to-End Journal Copy
Time.
