I created a kubernetes cluster with azure as explained in the https://docs.microsoft.com/en-us/azure/aks/tutorial-kubernetes-deploy-cluster with the command az aks create --resource-group myResourceGroup --name myAKSCluster --node-count 1 --generate-ssh-keys as described. I created the nodes as in the tutorial and then removed them. This means that I have the following result with the following command:
$ kubectl get services
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.0.0.1 <none> 443/TCP 19h
The problem is that even if I have only one cluster, I have a really big network usage and some cpu usage It's really big given that I'm using nothing in the services.

As you can see in the image, taken for only the last 12 hours, I have a network in of almost 1Gb and there's always a cpu usage of more than 13% for a process that it's mainly idle. Just for information, I started the cluster from scratch yesterday.
Does anyone knows where this comes from? And how can I debug it?
