Hello I have got a question about Istio Network Policies .

I created a network policy shown as below and tested it . It works .

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: api-policy
  namespace: point-1
spec:
  podSelector:
    matchLabels:
      run: api
  ingress:
  - ports:
    - protocol: TCP
      port: 80
    from:
    - podSelector:
        matchLabels:
          istio: ingress

In my case I want to log all requests all around the internal network , and track which request is blocked, denied according to the policy concerns ?

How Can I log the internal traffic activity in ISTIO .
