Help with container_memory_usage_bytes missing on a certain installation

[alexellis]

I started off by looking into containerd, and ended up here.

The container_memory_usage_bytes metric isn't showing on one of my installations, both are RHEL-like, but one has a custom Kernel for Firecracker.

I've added some notes on the original issue, but wanted to ask folks here if they knew why this metric would show on cadvisor when run directly, but not when running via the containerd integration?

I can run test commands on either host, and have some outputs already in the below issue to help
