This is something that might be best for it's own command (docker stats, docker capacity), but for now I'm proposing to keep it in the docker info command.

Ideally it would be really nice to expose more stats about the docker host via the API, so you can keep an eye on things remotely, and plan your capacity better. If you know how much more room a server has, you will know how many more containers you can deploy there.

This is what I would like to see.

• of containers installed

• of running containers

• Total RAM for all installed containers
• Total RAM used for running containers
• Total RAM installed on the server
• Free RAM available on server
• Total disk space used by all containers
• Available disk space ( size and percentage free for each mount point)
• CPU info (# of CPU's and Core's)
• Disk I/O stats
• Average CPU stats

While I'm asking this would be nice as well.

• List of public IP addresses available (ipv4, and ipv6)
