## CRI container and pod statistics without cAdvisor
This encompasses two related pieces of work (changes to the kubelet's `/metrics/cadvisor` endpoint and improvements to the replacement _summary_ API). *Corrections*: the feature CRI container and pod statistics without cAdvisor has been removed as it did not make the release.
There are two main APIs that consumers use to gather stats about running containers and pods: summary API and `/metrics/cadvisor`. The Kubelet is responsible for implementing the summary API, and cadvisor is responsible for fulfilling `/metrics/cadvisor`.
This enhances CRI implementations to be able to fulfill all the stats needs of Kubernetes. At a high level, there are two pieces of this:
- It enhances the CRI API with enough metrics to supplement the pod and container fields in the summary API directly from CRI.
- It enhances the CRI implementations to broadcast the required metrics to fulfill the pod and container fields in the `/metrics/cadvisor` endpoint.
