Expected behavior
A clear and concise description of what you expected to happen.

Your environment

  • Version of the Prometheus exporter - release version or a specific commit 0.11.0
  • Version of Docker/Kubernetes v1.23.6
  • [if applicable] Kubernetes platform (e.g. Mini-kube or GCP) rke
  • Using NGINX or NGINX Plus nginx

Additional context
Add any other context about the problem here. Any log files you want to share.

The metrics available from the Open Source version of NGINX are limited as mentioned in the readme.
If you want the full metrics that NGINX can bring you need to run the NGINX Plus version of the ingress controller which is this project: https://github.com/nginxinc/kubernetes-ingress

From the version of the ingress controller I believe your are running the Kubernetes Community version. Which is based on NGINX open source and requires the stub_status module.

Hi @brianehlert So if i was useing Open Source version of nginx , i can only get 9 metrics, right?

brianehlert commented

This is correct.
The open source version of NGINX has a limited set of metrics available.
This project calculates some of the metrics you are seeing and thus you technically have more than NGINX OSS by itself provides.
