[Help] Lower cAdvisor refresh interval

[SoerenHenning]

By default, cAdvisor metrics (https://<node-ip>:10250/metrics/cadvisor) such as pod CPU usage seem to be updated every 15-20 seconds. I would like to get these metrics more frequently and figured out that setting something like --housekeeping-interval 5s in the kublet start command should achieve this.

Unfortunately, I found no documentation on how to set this configuration via eksctl.

The following

#...
nodeGroups:
  - name: <node-type>
    # ...
    kubeletExtraConfig:
      housekeepingInterval: "5s"

does not seem to work, as the value is passed to /etc/kubernetes/kubelet/kubelet-config.json but is no known field for a KubeletConfiguration.

Is there any other way to pass a housekeeping-interval to the kubelet?
