Question 157

A user is displaying the CPU utilization, and Network in and Network out CloudWatch metrics data of a single instance on the same graph. The graph uses one Y- axis for CPU utilization and Network in and another Y-axis for Network out. Since Network in is too high, the CPU utilization data is not visible clearly on graph to the user. How can the data be viewed better on the same graph?

  1. It is not possible to show multiple metrics with the different units on the same graph
  2. Add a third Y-axis with the console to show all the data in proportion
  3. Change the axis of Network by using the Switch command from the graph
  4. Change the units of CPU utilization so it can be shown in proportion with Network
