Kindly help on this issue

@suryaachandra Thanks for trying out Kruize.

To help you out and better understand the issue I need some details which are mentioned below:

• I'm expecting you were running Kruize on minikube setup on a windows machine, Is my assumption correct?
• Can you please share us the output of kubectl -n monitoring describe pod <autotune pod name>
• Can I please know which demo you are trying? is it remote monitoring or local monitoring?
  (currently only remote monitoring demo works as we are working on developing the local monitoring use case)

3. Can I please know which demo you are trying? is it remote monitoring or local monitoring?
   **Steps followed for running the demo

1. downloaded the minikube
2. cloned the repo https://github.com/kruize/kruize-demos to local
