The graph intended to represent information about the migration process does not display the information correctly. (In my opinion)

4.14

Always

1. Do few live migration 
2. See if it make sense

As user/cluster admin, I care about the indeviduals migration, so I expect to clearly see when a migration start, how much data is left to migrate, the migration rate.
Also the dirty rate have diffrent unit, which should not share the same Y-axis with data processed.
Also, it seems the matrics just keep piling up, a small VM which 2G RAM can show with 5TB data processed, after several migration. Which makes the graph less understandable and intuitive.

Included a screenshot, for example, you would assume "Data remmining" will start high, and go down as you advnace, but that is not the case.
