Introduction to Telemetry Relay

Use Telemetry Relay to forward telemetry to destinations outside of CoreWeave

Telemetry Relay is a fully-managed solution for forwarding telemetry, like logs and metrics, to destinations outside of CoreWeave's observability platform. Telemetry Relay has the following features and benefits:

  • Comprehensive data aggregation: Ingests telemetry data from multiple sources.
  • Flexible data filtering and routing: Allows fine-grained data filtering before sending to configured endpoints.
  • Guaranteed delivery: High SLOs for data completeness and latency.
  • Fully managed with easy configuration: Zero-operational overhead for configuring data filters and endpoint routing.

By supporting multiple data streams to a variety of destination endpoints, Telemetry Relay provides flexibility for managing and analyzing your data.

  • Streams: Pre-defined telemetry categories, for example, application logs or system metrics.
  • Pipelines: A configuration that links a stream to an endpoint.
  • Endpoints: Destinations, for example, S3, Prometheus, HTTPS.

Supported logs and metrics​

The table below lists the supported logs and metrics for forwarding:

StreamData
Audit LogsCKS audit logs
CoreWeave API audit logs
Console audit logs
Support Access Management logs
Application LogsCustomer CKS Pod logs
Platform LogsCKS Control Plane logs (other than audit logs, for example etcd logs, controller manager logs)
CKS system component logs (for example, CSI, CNI)
Node logs (for example, kernel logs)
Network fabric logs
Platform MetricsCKS Control Plane metrics
Redfish metrics
Ethernet routing metrics
Ethernet interface metrics
BMC (Node and DPU) metrics
NVswitch metrics
DCGM metrics

Telemetry Relay does not support forwarding application metrics. To forward application metrics, see the Forward Application metrics page.

Supported endpoints​

You can route logs and metrics to the following endpoints:

  • S3-compatible endpoint, such as CoreWeave AI Object Storage (for logs)
  • HTTPS endpoint (for logs)
  • Prometheus Remote Write v1.0+ (for metrics)

Configure Telemetry Relay​

To set up and configure Telemetry Relay, contact Support in order to define the following:

  • Data streams
  • Forwarding and filtering requirements
  • Destination endpoints
