What happened?

I followed the tutorial and found that the training was incorrect and promethus did not have the nginx_ingress_controller_requests_rate indicator.

What did you expect to happen?

success to train the model

How can we reproduce it (as minimally and precisely as possible)?

Anything else we need to know?

nginx_ingress_controller_requests_rate is not a real metrics but an alias of the metrics rule above, so you won't find it in Prometheus.

Could you share the contents of your train config yaml?
