In this case (ingress controller) this is done with a Prometheus metric exporter. So all the metrics are available in Prometheus.
It sounded like there's a config directive to have Ingress Controller push all its metrics into Prometheus?
If it's helpful at all, here's a concrete example of a k8s nginx setup that exports-to/is-monitored-by prometheus: https://github.com/bitnami/kube-manifests/blob/master/common...

Does anyone know how to effectively keep a tab on this on a docker container running nginx open source? I have an external log/metrics monitoring server that could alert on this, but I'm asking more on the lines of how to get this information to the monitoring server.
