Docker Host Disk Monitoring Recommendations

Hey All,

Wondering if anyone here has had any experience monitoring hosts with docker containers?  We're just starting to monitor some of our CoreOS hosts.  SNMP is executing within a docker container on the host, and is mapping the physical /dev/sda disk to several file system mount points. For example (/etc/resolv.conf, /etc/hosts).  Unfortunately this is not accurate, and I'm not sure why it mounts or detects those files as disks.  It does accurately represent how much disk is being used, but I don't really need 5 'disks' reporting back the same data.  Anyone have some ideas or thoughts on how I can get this cleaned up for just our CoreOS docker environment?  Thanks!
