# Service levels and limits

> Service level objectives, retention limits, and log size limits for CoreWeave Observe

[CoreWeave Observe™](/observability) 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.

<Note>
  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                                                                                                                                                                                                                                                                                  |

## 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        |

## 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 |
