What is Ctop?

Editorial review
ctop is a command-line tool that provides an interactive, real-time interface for monitoring containers. It's designed for developers, system administrators, and anyone working with Docker or runC who needs quick insights into their containerized applications. Similar to 'top' for system processes, ctop offers a dynamic view of container metrics, allowing users to easily track CPU usage, memory consumption, network I/O, and more. This tool simplifies the process of observing container performance and health directly from the terminal. Its intuitive interface and real-time updates make it an invaluable asset for debugging performance issues, ensuring resource allocation, and generally maintaining the operational efficiency of container deployments. It's particularly useful in environments where a lightweight, immediate monitoring solution is preferred over more complex graphical dashboards.
