What information does the docker stats command provide?

The docker stats command presents a live stream of resource usage statistics for running containers, offering insights into how much CPU, memory, network I/O, and block I/O each container is consuming. This command is crucial for monitoring the performance and resource allocation of containers in real-time, allowing developers and system administrators to optimize resource usage and troubleshoot performance issues effectively.

In contrast, the other choices do not accurately describe the function of the docker stats command. For instance, the first choice is focused on listing containers rather than providing live statistics. The third option pertains to logging command history, which is unrelated to resource usage monitoring. Similarly, the last choice involves network connections, which falling outside the scope of what docker stats reports. Hence, option B is the correct choice, as it best represents the primary functionality of the docker stats command.
