Forward application metrics

To forward CoreWeave Kubernetes Service (CKS) metrics to an external system, deploy the Prometheus Agent inside your CKS cluster and configure it to use remote-write.

CKS clusters deployed before July 7, 2025 have Prometheus Operator pre-installed.CKS clusters deployed after July 7, 2025 don’t have Prometheus Operator pre-installed. Clusters deployed after this date must install Prometheus Operator before proceeding with the following steps.

To deploy the Prometheus Agent in your CKS cluster, complete the following steps:

Choose a namespace to deploy the Prometheus Agent in. You can deploy the Prometheus Agent to an existing namespace, or create a new namespace with kubectl. To create a new namespace, replace [NAMESPACE-NAME] with your chosen namespace and run:
kubectl create namespace "[NAMESPACE-NAME]"
Configure the Prometheus Agent CustomResource YAML file with your remote-write destination, as in the following example:
sample-prometheus-agent.yaml
apiVersion: monitoring.coreos.com/v1alpha1 kind: PrometheusAgent metadata: name: my-prom-agent namespace: "[NAMESPACE-NAME]" spec: remoteWrite: - url: "https://example-url/api/v1/write" ...
For more information about remoteWrite configurations, see the Prometheus Operator API reference.
To deploy the Prometheus Agent to your CKS cluster, replace sample-prometheus-agent.yaml with the appropriate filename and run:
kubectl apply -f sample-prometheus-agent.yaml
Metrics generated within your CKS cluster now remote-write to your specified destination.
