Trouble monitoring nginx-ingress with prometheus

Pardon my ignorance as I’m new to Kubernetes. I’m trying to monitor my nginx-ingress using prometheus.

I initially installed the ingress using this tutorial which has you install the helm stable/nginx-ingress chart.

Then I installed the Kubernetes Monitoring Stack

Next I discovered you needed to enable metrics on the ingress-controller to expose them to prometheus. I used helm upgrade to set controller.metrics.enabled on the ingress. This had the effect of creating a new service nginx-ingress-controller-metrics but still no stats in prometheus.

Finally, I found this issue which said you needed to create a prometheus job to scape the ingress metrics. Unfortunately, it didnt say how to add the job. Since the monitoring stack uses promethius-operator I ended up following this method to add the job (i think). Following these instructions I created a secret of the job as outlined in the stack overflow answer, added that secret to the promethius-operator namespace, then referenced it in spec.additionalScrapeConfigs on prometheus-operator-prometheus

That’s where I’m at now and still no luck seeing the ingress metrics. Any guidance would be much appreciated. Thanks in advance!
