Where is the kubelet on AWS EKS?

Question

Our AWK EKS cluster does not seem to have 'kubelet' pods or any pod containing the label k8s-app=kubelet. Therefore, monitoring the cluster, we're missing some metrics like container_cpu_usage_seconds_total which, as far as I can track, should have been provided by cAdvisor via a kubelet pod.

Our AWK EKS only has aws-node-xxxxx, coredns-xxxxxxxxx-xxxxx and kube-proxy-xxxx pods in the kube-system namespace.

I looked up the metrics of the aws-node, but this does not contain the container_cpu_usage_seconds_total metric.

Any idea why there is no kubelet pod on EKS? I thought it is quite basic, so it should be there somehow. Is it hidden? Can it be accessed for metrics?
How to get metrics like container_cpu_usage_seconds_total on EKS?

Kubelet作为EKS工作程序节点内的systemd守护程序运行。您可以通过SSH进入EC2工作实例，然后尝试运行“ systemctl status kubelet”来确认这一点。
