CPU usage tracking doesn't seem to work

[vincentwoo]

I'm on Ubuntu 13.04 x64, using docker. I can hit /:name/mem to get what seem like accurate memory counts, but /:name/cpu seems to always return 0.

I'm looking at that issue as soon as I can ;-)

Ok I've worked a bit on that, Sorry for the long time.
I've added some debug and allow short container id.

Everything seems to work correctly:

└> curl http://localhost:4244/containers/c3e8cc51df10/mem
4788224
└> curl http://localhost:4244/containers/c3e8cc51df10/cpu
18

Wait a second

└> curl http://localhost:4244/containers/c3e8cc51df10/cpu
16
