   I get the metrics by doing this (environment runs in a k8s cluster):
   
   ```
   1. kubectl port-forward kpf -n apisix service/apisix-prometheus-metrics 9091
   2. curl http://localhost:9091/apisix/prometheus/metrics
   ```
   
   The result is this, where I'd exert to see the missing metrics?
   
   ```
