See https://kep.k8s.io/2371 * Implement new CRI RPCs - `ListPodSandboxStats` and `PodSandboxStats` * `ListPodSandboxStats` and `PodSandboxStats` which return stats about pod sandbox. To obtain pod sandbox stats, underlying metrics are read from the pod sandbox cgroup parent. * Process info is obtained by calling into the underlying task * Network stats are taken by looking up network metrics based on the pod sandbox network namespace path * Return more detailed stats for cpu and memory for existing container stats. These metrics use the underlying task's metrics to obtain stats. Signed-off-by: David Porter <porterdavid@google.com>
