Metrics

Fully managed Prometheus metrics available for your cloud environment.

On CoreWeave, a wide range of Prometheus metrics are made available by default. The following guides presume that you already have an active CoreWeave account including a functioning API Access Token.

Once logged in to your CoreWeave Cloud account, visit the Prometheus dashboard at https://prometheus.ord1.coreweave.com.

API key authentication

To authenticate using HTTP, access the Prometheus server by sending your Access Token as the Authorization Header value in the HTTP request.

Parameter	Value
Methods	GET or POST
Header	Authorization
Value	Bearer <TOKEN>
URL	https://prometheus.ord1.coreweave.com/

note

Replace <TOKEN> with your CoreWeave Access Token.

Example Prometheus query using an Access Token

POST https://prometheus.ord1.coreweave.com/api/v1/query

Example usage for sending a request to the Prometheus API using your Access Token.

Query Parameters

Name	Type	Description
time	number	Unix timestamp of current time
query	string	The PromQL Query (kube_pod_container_info)

Headers

Name	Type	Description
Authorization	string	Set value to Bearer <TOKEN> as the value, replacing <TOKEN> with your CoreWeave Access Token.

Example request

$ curl -X POST 'https://prometheus.ord1.coreweave.com/api/v1/query?time=<UNIX_TIMESTAMP>&query=<PROMQL_QUERY>' \
-H 'Authorization: Bearer <TOKEN>'

Responses

Value	Type	Description

Custom metric scraping

CoreWeave's hosted Prometheus service may be used to scrape custom targets using a ServiceMonitor. Annotations from the ServiceMonitor must match the Service hosting the Prometheus exporter endpoint, usually at the path /metrics.

Below is an example of a Prometheus exporter scraped by the Prometheus service.

important

The value of .endpoints.port must be the literal string http, and may not be replaced with a port number integer (e.g., 80).
