The RealTheory Collector requires the Metrics Server to be installed on the Kubernetes cluster. ## Solution The Metrics Server is automatically installed with some managed versions of Kubernetes. The following table indicates which managed Kubernetes offerings include the Metrics Server as part of the standard offering. | Managed Kubernetes Offering | Includes Metrics Server | More Information | | --- | --- | --- | | AKS | Yes | | | GKE | Yes | | | EKS | No | [How to install the Metrics Server on EKS](https://docs.aws.amazon.com/eks/latest/userguide/metrics-server.html) | ### Procedure There are multiple ways to check if your cluster is running the Metrics Server: 1. Run the following command: ``` kubectl get deployment metrics-server -n kube-system ``` If the Metrics Server is installed, the output will be similar to the following example: ``` NAME READY UP-TO-DATE AVAILABLE AGE metrics-server 1/1 1 1 25h ``` 2. Alternatively, run the following command: ``` kubectl get --raw "/apis/metrics.k8s.io/v1beta1/nodes" ``` If the Metrics Server is installed, the output will be similar to the following example: ``` {"kind":"NodeMetricsList","apiVersion":"metrics.k8s.io/v1beta1","metadata":{"selfLink":"/apis/metrics.k8s.io/v1beta1/nodes"},"items":\[{"metadata": {"name":"cirrus12","selfLink":"/apis/metrics.k8s.io/v1beta1/nodes/cirrus12", "creationTimestamp":"2019-08-08T23:59:49Z"},"timestamp":"2019-08-08T23:59:08Z", "window":"30s","usage":{"cpu":"1738876098n","memory":"8406880Ki"}}\]} ``` 3. If the Metrics Server is not installed, see [How To Install or Upgrade the Metrics Server](/v1/docs/how-to-install-or-upgrade-the-metrics-server). **See Also** [How To Install or Upgrade the Metrics Server](/v1/docs/how-to-install-or-upgrade-the-metrics-server)
