Hi,  
I’ve got to different rancher nodes, one running ubuntu 16.04 LTS and docker 1.11.1 and the other is a rancherOS 0.4.5 docker 1.10.3.  
Both running the same apps.

ubuntu is showing used memory as 3.13GB and rancherOS is showing 1.86GB (both having mem=4GB).

How am I supposed to interpret this info?

Maybe related,  
none of the apps are showing stats info on ubuntu hosts…

br hw

Our integration with cAdvisor doesn’t work with Docker 1.11 + systemd (16.04).

Grab `cat /proc/meminfo` from both?
