What do you want us to build?
When I enable Networ policy feature for VPC CNI, Network policy Controller runs on EKS control plane. As a user, I do not have access to the NP controller running on controlplane.

I need access for np controller logs and metrics similar to apiserver logs, apiserver audit logs.

**Which service(s) is this request for?**
EKS

Start by reviewing how the EKS network policy controller runs on the control plane and how users access existing API server and audit logs. The work is complete when users can access network policy controller logs and metrics through comparable EKS-supported interfaces.
