Conversation
The cgroupstats provides information from taskstats which help us to know how `busy` tasks in one cgroup are right now. With Metric API in shim, it can enhance monitor capability.

So these stats are provided via a netlink socket? |

Yes. It seems efficient I think. |

Where is the implementation going to come from? the Shims? |

Yes. It is for kata container. We put the collector in the agent. It will export the data through Mertic Shim API. |

We decide to use metric-server get load information instead of using cadvisor(we make runc and kata provide load information, and passed by shim metric interface). So add a interface in containerd/cgroup libbrary. |
