EKS implementation

Hi,
I have some questions about the EKS implementation:

  1. Why when implementing a cluster I don’t get the performance metrics, as if I get it from AKS?
  2. I cannot determine the volume of the worker nodes in the implementation, an option that the AWS console allows
  3. How can I determine the number of maximum pods in the deployment? or is that determined by the size of the EC2?
