Introduction to Telemetry Relay

Use Telemetry Relay to forward logs and metrics

Telemetry Relay is a fully-managed solution for forwarding logs and metrics to destinations outside of CoreWeave's observability platform with 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.

Supported logs and metrics

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

Stream	Data
Audit Logs	CKS audit logs CoreWeave API audit logs Console audit logs Support Access Management logs
Application Logs	Customer CKS Pod logs
Platform Logs	CKS 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 Metrics	CKS Control Plane metrics Redfish metrics Ethernet routing metrics Ethernet interface metrics BMC (Node and DPU) metrics NVswitch metrics DCGM metrics

Supported endpoints

You can route logs and metrics to the following endpoints:

• HTTP
• Prometheus Remote Write v1.0+

Configure Telemetry Relay

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

• Data streams
• Forwarding and filtering requirements
• Destination endpoints

Limitations

Note that Prometheus metrics from your application workloads are not included in Telemetry Relay. In general, CoreWeave Observe™ does not ingest application workload metrics. If you're interested routing application workload metrics, see Application Metrics Forwarding.
