Support for cgroupv2

[dipti262]

Hi ,

Could you please let me know if there is support for cgroupv2 in the current sriov-network-metric-exporter?
I am currently using the latest commit for sriov-network-metric-exporter (master).

Thanks

@dipti262 Do you have a specific OS and sys/fs path that can be used for validation testing.

[dipti262]

Hi @oreillymj
The OS that we work on is Suse Enterprise Linux. But it can be tested on OpenSUSE.

PS: Pardon me for the late reply.

@dipti262 - The recent release https://github.com/k8snetworkplumbingwg/sriov-network-metrics-exporter/releases/tag/v1.0.0 was tested on Ubuntu 22.04 with cgroupsv2. It requires a change of the host sys/fs path in the daemonset configuration.
Would like feedback on your experience of where kubepods.slice resides on OpenSUSE.

hostPath:
path: /sys/fs/cgroup/cpuset/kubepods.slice/
