@stensonb, @dzavalkinolx, @andrewsykim have all said that in cAdvisor v0.25.0 (or kubernetes v1.5.6 or v1.6.0) that they still have issues with disappearing metrics.

To help us get to the bottom of this, please provide OS, OS version, and cadvisor/kubernetes version. I suspect that this is a variant of #1572, which is caused by incorrectly adding the "container": "/system.slice/var-lib-docker-containers-acf76f8a0cf47638f7ab7c7e033872672479017f7447f90d2d6d6d5c39bf7536-shm.mount". See #1572 for more details. Please check your logs for other containers that could have been added incorrectly.
