What does the docker stats command do?

The docker stats command is designed to give users real-time statistics regarding the resource usage of active containers. When executed, it displays key performance metrics such as CPU usage, memory usage, network IO, and block IO for each running container. This information is invaluable for monitoring container performance and ensuring that applications are running efficiently. Docker stats allows users to assess resource allocation and make necessary adjustments to optimize performance or troubleshoot issues. It's a fundamental tool for anyone managing Docker containers, especially in production environments where resource utilization is critical.
