### About managed NGINX Ingress deployments
NGINX Ingress is deployed into the `gitlab-managed-apps` namespace, using the [official Helm chart](https://github.com/helm/charts/tree/master/stable/nginx-ingress). NGINX Ingress will be [externally reachable via the Load Balancer's Endpoint](../../../clusters/applications.md#ingress).

### Manually setting up NGINX Ingress for Prometheus monitoring
Version 0.9.0 and above of [NGINX Ingress](https://github.com/kubernetes/ingress-nginx) has built-in support for exporting Prometheus metrics. To enable, a ConfigMap setting must be passed: `enable-vts-status: "true"`. Once enabled, a Prometheus metrics endpoint will start running on port 10254.

## Specifying the Environment label
In order to isolate and only display relevant metrics for a given environment, GitLab needs a method to detect which labels are associated. To do this, GitLab will search for metrics with appropriate labels. In this case, the `upstream` label must be of the form `<KUBE_NAMESPACE>-<CI_ENVIRONMENT_SLUG>-*`.

If you have used [Auto Deploy](../../../../topics/autodevops/stages.md#auto-deploy) to deploy your app, this format will be used automatically and metrics will be detected with no action on your part.
