How does the engineer see if the new release lowered average memory utilization?

A Software Engineer is troubleshooting an issue with memory utilization in their application.

Answer: C

Explanation:

The correct answer is C. On the chart for plot A, select Add Analytics, then select Mean: Aggregation.

In the window that appears, select ‘version’ from the Group By field.

This will create a new plot B that shows the average memory utilization for each version of the application. The engineer can then compare the values of plot B for the ‘canary’ and ‘stable’ versions to see if there is a significant difference.
