## Configuring Prometheus to monitor for Kubernetes node metrics
## Configuring Prometheus to monitor for Kubernetes metrics
In order for Prometheus to collect Kubernetes metrics, you first must have a
Prometheus server up and running. You have two options here:
Prometheus needs to be deployed into the cluster and configured properly in order to gather Kubernetes metrics. GitLab supports two methods for doing so:
- If you have an Omnibus based GitLab installation within your Kubernetes cluster, you can leverage the bundled Prometheus server to [monitor Kubernetes](../../../../administration/monitoring/prometheus/index.md#configuring-prometheus-to-monitor-kubernetes).
- To configure your own Prometheus server, you can follow the [Prometheus documentation](https://prometheus.io/docs/introduction/overview/) or [our guide](../../../../administration/monitoring/prometheus/index.md#configuring-your-own-prometheus-server-within-kubernetes).
- GitLab [integrates with Kubernetes](../../project/clusters/index.md), and can [deploy Prometheus into a connected cluster](../prometheus.html#managed-prometheus-on-kubernetes). It is automatically configured to collect Kubernetes metrics.
- To configure your own Prometheus server, you can follow the [Prometheus documentation](https://prometheus.io/docs/introduction/overview/).
