Version 0.9.0 and above of NGINX Ingress have 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 starts running on port 10254.
Next, the Ingress needs to be annotated for Prometheus monitoring. Two new annotations need to be added:
Managing these settings depends on how NGINX Ingress has been deployed. If you have deployed via the official Helm chart, metrics can be enabled with
controller.stats.enabled along with the required annotations. Alternatively it is possible to edit the NGINX Ingress YAML directly in the Kubernetes dashboard.
To isolate and display only relevant metrics for a given environment, GitLab needs a method to
detect which labels are associated. To do this, GitLab searches for metrics with appropriate labels.
In this case, the
ingress label must include the value
