How to tune kublet to reduce the cpu consumption

Hi Team,
We are currently using k8s 1.21.0 and found cpu consumption by kubelet is very high, I am looking for the way/configuration how to reduce the cpu consumption by kubelet.

Cluster information:

Kubernetes version: 1.21.0
Cloud being used: bare-metal
Host OS: SUSE Linux
Installation method:
CNI and version:
CRI and version:

More details would be necessary.

  • What qualifies as very high CPU usage for you? (How are you measuring this?)

  • Do you have any details on the cause of the CPU usage? (Have you gathered any kubelet logs or enabled the flag for verbose logging to get some insight on what’s happening?)

  • What install method did you use for your cluster? (k3s is going to require less resources than the kubeadm install)
