/kind bug

What happened:
All cadvisor container_fs_* stats are 0, except a few without pod/image labels which I assume are for the root cgroup:

What you expected to happen:
Have these stats return right values..

How to reproduce it (as minimally and precisely as possible):
As far as I can tell, this should happen on a fresh install too.

Environment:

  • Kubernetes version (use kubectl version): 1.8.1
  • Cloud provider or hardware configuration: GKE

@discordianfish I'm seeing similar behavior. Let me know if you've resolved it?

@bpownow Unfortunately I haven't found a fix. Right now I'm just not looking at these metrics. If I had to fix them, I'd probably look into running cadvisor standalone or revive my container_exporter
