The Docker Container Summary view displays the following data:

Resource Utilizations: The resource utilization for the selected Docker Container over a selected period of time, which includes the following:
CPU Load: Shows the CPU utilization of the selected container.
Network Transfer: Shows the transfer bytes rate of the selected container over a selected period of time.
Memory: Shows the memory utilization of the selected container.
Disk Transfer: Shows the disk transfer bytes rate of the selected container over a selected period of time.
Summary and Resource Information: Displays the detailed information about the selected Container, including State, Command, Created Time, Started Time, Image, and so on.

Click Explore on the upper right of the Docker Container Summary view to open the Container Explorer view, which shows more detailed information about this container.
