ctop: A Go repository from ppabc

Top-like interface for container metrics

ctop provides a concise and condensed overview of real-time metrics for multiple containers:

as well as an single container view for inspecting a specific container.

ctop comes with built-in support for Docker and runC; connectors for other container and cluster systems are planned for future releases.
