nomad_1.3.0-beta.1 - memory stats shows 0 with cgroupv2

[Oleksii-Melnyk-UA]

Nomad version

nomad_1.3.0-beta.1

Operating system and Environment details

Flatcar 3033.2.2
https://www.flatcar.org/releases/#release-3033.2.2

Issue

I used previously Flatcar version 2765.2.1 and nomad 1.0.4. At that time I could see memory metric for containers provided by Nomad.
But after update to Flatcar 3033.2.2, memory metric always shows 0.
I assumed that the reason is that new Flatcar version become using cgroupsv2.
Found similar issue - #10251

So, I updated Nomad version to 1.3.0-beta.1 .
But with 1.3.0-beta.1 memory metric still shows 0.

Can you, please, help to fix this issue.

@Oleksii-Melnyk-UA thanks for experimenting with the Nomad 1.3 beta.

Are you able to reproduce the problem using the rc.1 release?
https://releases.hashicorp.com/nomad/1.3.0-rc.1

memory metric always shows 0

What specifically are you looking at that you expect to be non-zero?

What task driver are you using? Can you share a minimal job file that reproduces the problem?

Found that see memory metric on 1.3.0-rc.1 nomad release using command:
nomad status job_name
nomad alloc-status alloc-id
