The command 'docker stats' is designed to display real-time resource usage statistics for running Docker containers. When you execute this command, it provides metrics such as CPU usage, memory usage, network I/O, and disk I/O for each container. This functionality is crucial for monitoring the performance of containers and ensuring that they are operating within expected resource limits.

By providing these statistics, 'docker stats' enables users to diagnose performance issues, identify which containers are consuming excessive resources, and make informed decisions about resource allocation and scaling. It is particularly advantageous in production environments where performance and resource management are vital for maintaining service quality and availability.

The other options, while related to Docker functionality, do not pertain to what 'docker stats' specifically does. For example, network configurations, deleting containers, and listing images are managed by different commands, each serving a unique purpose within the Docker ecosystem.
