Scraping at a high frequency means that you end up with greater granularity of the gauge's signal, which can be then used to calculate SLOs. The /metrics/slis endpoint provides the raw data necessary to calculate an availability SLO for the respective Kubernetes component. CRI Pod & Container Metrics Collection of Pod & Container metrics via the CRI. FEATURE STATE: Kubernetes v1.23 [alpha] The kubelet collects pod and container metrics via cAdvisor . As an alpha feature, Kubernetes lets you configure the collection of pod and container metrics via the Container Runtime Interface (CRI). You must enable the PodAndContainerStatsFromCRI feature gate and use a compatible CRI implementation (containerd >= 1.6.0, CRI-O >= 1.23.0) to use the C

RI based collection mechanism. CRI Pod & Container Metrics With PodAndContainerStatsFromCRI enabled, the kubelet polls the underlying container runtime for pod and container stats instead of inspecting the host system directly using cAdvisor. The benefits of relying on the container runtime for this information as opposed to direct collection with cAdvisor include: Potential improved performance if the container runtime already collects this information during normal operations. In this case, the data can be re-used instead of being aggregated again by the kubelet. It further decouples the kubelet and the container runtime allowing collection of metrics for container runtimes that don't run processes directly on the host with kubelet where they are observable by cAdvisor (for example: container runtimes that use virtualization).•

Node metrics data Mechanisms for accessing metrics at node, volume, pod and container level, as seen by the kubelet. The kubelet gathers metric statistics at the node, volume, pod and container level, and emits this information in the Summary API . You can send a proxied request to the stats summary API via the Kubernetes API server. Here is an example of a Summary API request for a node named minikube : kubectl get --raw "/api/v1/nodes/minikube/proxy/stats/summary" Here is the same API call using curl: # You need to run "kubectl proxy" first # Change 8080 to the port that "kubectl proxy" assigns curl http://localhost:8080/api/v1/nodes/minikube/proxy/stats/summary Note: Beginning with metrics-server 0.6.x, metrics-server queries the /metrics/resource kubelet endpoint, and not /stats/summary . Summary metrics API source By default, Kubernetes fetches node summary metrics data using an embedded cAdvisor that runs within the kubelet. If you enable the PodAndContainerStatsFromCRI fe

ature gate in your cluster, and you use a container runtime that supports statistics access via Container Runtime Interface (CRI), then the kubelet fetches Pod- and container-level metric data using CRI , and not via cAdvisor. What's next The task pages for Troubleshooting Clusters discuss how to use a metrics pipeline that rely on these data. Kubernetes Metrics Reference Details of the metric data that Kubernetes components export. Metrics (v1.29) This page details the metrics that different Kubernetes components export. You can query the metrics endpoint for these components using an HTTP scrape, and fetch the current metrics data in Prometheus format
