Hi @haircommander |

would love to see some unit tests, and maybe even a POC of it being used in an end user project like CRI-O |

I have added the unit tests
I'm not very familiar with codebase of CRI-O, but I can get a quick POC in |

This adds methods to retrieve statistics for individual cgroup controllers (CPU, memory, pids, IO, hugetlb, rdma, misc) instead of requiring all stats to be fetched at once. This enables tools like cadvisor to collect specific metrics with different housekeeping intervals, reducing computational overhead.

Thanks @haircommander and @kolyshkin for the approvals. |

Technically, we have 2 approvals (@haircommander is a maintainer here, the status is not shown because he's not a member of opencontainers org, which I don't know how to fix), so I am going to merge this by the end of this week unless there are new objections/comments. |

I seem to have approval power now, do we manually merge or is there a bot that does it after 2 approvals? |

@AkihiroSuda any last minute review comments? |
