## 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](../../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/).
## Specifying the Environment

Instead, the [Deployment](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/) or [DaemonSet](https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/) name should begin with [CI_ENVIRONMENT_SLUG](../../../../ci/variables/README.md#predefined-variables-environment-variables). It can be followed by a `-` and additional content if desired. For example, a deployment name of `review-homepage-5620p5` would match the `review/homepage` environment.
If you are using [GitLab Auto-Deploy](../../../../ci/autodeploy/index.md) and one of the two [provided Kubernetes monitoring solutions](../prometheus.md#getting-started-with-prometheus-monitoring), the `environment` label will be automatically added.
## Displaying Canary metrics
> Introduced in [GitLab 10.2](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/15201).
GitLab also gathers Kubernetes metrics for [canary deployments](../../canary_deployments.md), allowing easy comparison between the current deployed version and the canary.
These metrics expect an `environment` label of the form `$CI_ENVIRONMENT_SLUG-canary` to isolate the canary metrics. If you are using [GitLab Auto-Deploy](../../../../ci/autodeploy/index.md), this label will be automatically configured for you.
These metrics expect the [Deployment](https://kubernetes.io/docs/concepts/workloads/controllers/deployment/) or [DaemonSet](https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/) name to begin with `$CI_ENVIRONMENT_SLUG-canary`, to isolate the canary metrics.
