Looking for a metric that represents the values in the size column:

$ sudo docker ps -s
CONTAINER ID        IMAGE               COMMAND              CREATED             STATUS              PORTS               NAMES               SIZE

@natoscott anything like that already available? couldn't find anything under containers.*

@spiermar I'm looking, but haven't uncovered where this information can be found yet (we definitely do not export this information from PCP today). We might need to start augmenting the data we provide now with additional metrics from the Docker REST API (if that's where it lives).

Couldn't find it in the pseudo-files, but I might be missing something.

GET /containers/(name)/json?size=1 will return the size in the SizeRw and SizeRootFs fields.
