the ingress resource stop to sync? what event indicates there? – Nginx

I run the ingress controller and put one annotation for round_robin algorithm to run. but seems there is no event run there. is it ok if no event in my ingress description? what event indicates there?

# kubectl describe ingress -n ingress

Name:             nginx-ingress

I deploy my ingress with this bro, and I have my ingress class. update 1.

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: nginx-ingress
  namespace: ingress
  annotations:
      nginx.ingress.kubernetes.io/load-balance: ewma
spec:
  ingressClassName: nginx
  rules:
  - host: service.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: service1
            port:
              number: 80
      - path: /service2
        pathType: Prefix
        backend:
          service:
            name: service2
            port:
              number: 80
      - path: /service3
        pathType: Prefix
        backend:
          service:
            name: service3
            port:
              number: 80
