We have this “problem” in all our hosts, the memory displayed using TOP and Rancher GUI is not the same, for example:
Host with 10Gb ram:
- using TOP we get 750mb free and the rest is used
- using Rancher GUI we get only 4.34GB used
If we do a docker stats and sum all memory used it’s almost TOP says and not what Rancger GUI says.
Rancher Version: 1.4.2
Docker Version: 1.12.6
OS and where are the hosts located? (cloud, bare metal, etc): CoreOS 1298.6.0
What we’re missing here?
