Prometheus can't get data from nginx-ingress controller


I just installed prometheus-server in my cluster according to this tutorial:

The prometheus-server deployment has already been running successfully. I’m able to open the dashboard from my browser. But, when I tried to execute a query like on the tutorial example, I can’t find the suggestions query like the tutorial shows.

There are no suggestion nginx_ingress_controller_* .

Expected result:

Is there anything wrong with my prometheus config?
