Metrics for basic Docker stats (number of containers, images, volumes)

[mfriedenhagen]

As a node responsible I would like to see gauges for

• number of containers
• number of running containers
• number of stopped containers
• number of images
• number of tagged/untagged images
• number of volumes
• number of dangling volumes
• number of networks
• number of dangling networks
• equivalent of docker system df in newer docker versions

so that I may easily see when my cleanup jobs do not succeed

While the Prometheus metrics provided for running containers are nice and informative, I truly miss an overview for a node.

I was just looking for this as well. Looking to get some metrics for how much disk space is used by images, containers, etc.
