Service levels and limits - CoreWeave Docs

CoreWeave Observe™ sets best-effort service level objectives (SLOs) for the availability, latency, and durability of its observability services, and applies limits to telemetry retention and log line size. This page lists those service levels and limits. Service level objectives are the targets that CoreWeave aims to meet for each service, covering the availability and latency of your queries and the durability of your stored logs and metrics.

These service levels and limits are best-effort product performance guidelines.

Service level objectives

The following table lists the service level objectives for CoreWeave observability services. Availability targets apply to real customer traffic, and query endpoints are reached through observe.coreweave.com.

Service	SLO measurement
CoreWeave Grafana	99.9% of all requests to CoreWeave Grafana complete successfully.
Logs query	Availability: 99.9% of all requests through `observe.coreweave.com` complete successfully. Response latency: 99% of log queries return results within 1 minute. Retention: 99.999% of audit logs are retained for 3 months. 99.999% of other logs are retained for 7 days.
Metrics query	Availability: 99.9% of all requests through `observe.coreweave.com` complete successfully. Response latency: 99% of metric queries spanning 7 days at a 1-minute step return within 5 seconds. Retention: 99.999% of metrics are retained for 3 months.

For information about querying logs and metrics through these endpoints, see Query Logs and Metrics.

Retention limits

CoreWeave retains telemetry based on the limits described below. Data older than the retention limit may no longer be queryable.

Telemetry type	Retention limit
Audit logs	3 months
Other logs (platform and application logs)	7 days
Metrics	3 months

For use cases that require longer retention, such as audit logs, see Configure Telemetry Relay to forward telemetry to an external destination.

Log size limits

Individual log lines are subject to a maximum size. Log lines that exceed the limit may be dropped or truncated.

Limit	Size
Log line size limit	256 KB
Telemetry Relay log line size limit	100 KB
