I installed nginx and nginx exporter successfully using https://sysdig.com/blog/monitor-nginx-prometheus/

Now I want to enable stub stat metrics,

Here is the config map :

apiVersion: v1
data:
  nginx.conf: |
    events {}
    http {
        server {
            listen 80;
            location / {
                return 200 "hello worldn";
            }
            location /stub_status {
                stub_status;
                allow 127.0.0.1;  # Only allow local access
                deny all;  # Deny all other access
            }
        }
    }
kind: ConfigMap
metadata:
  creationTimestamp: "2024-07-31T07:30:42Z"
  name: nginx-config
  namespace: rda-dev
  resourceVersion: "450759929"
  uid: a84a8da8-90c1-4619-b972-e60b1a32a784

Here is the K8s deployment :

spec:
      containers:
      - image: nginx:latest
        imagePullPolicy: Always
        name: nginx
        ports:
        - containerPort: 80
          protocol: TCP
        - containerPort: 443
          protocol: TCP
        resources: {}
        terminationMessagePath: /dev/termination-log
        terminationMessagePolicy: File
        volumeMounts:
        - mountPath: /etc/nginx/nginx.conf
          name: nginx-config
          subPath: nginx.conf
      - args:
        - --nginx.scrape-uri=http://localhost/stub_status
        - --nginx.plus
        image: nginx/nginx-prometheus-exporter:latest
        imagePullPolicy: IfNotPresent
        name: nginx-exporter
        ports:
        - containerPort: 9113
          protocol: TCP
        resources:
          limits:
            cpu: 500m
            memory: 128Mi

I am able to see common metrics on my Prometheus but not able to see the stub stat metrics.

What configuration I am missing here?
